so? I ssuspect, that single photon pressure must be h/c^2 or h*f/c^2. And measurment units must be like momentum p=m*v. Newtons?
excaza
Um...pressure is Force per unit area. Pressure has absolutely nothing to do with momentum, did you think that because they both have a p? The units of momentum are not Newtons, they are kg*m/s
DavidD
QUOTE (excaza+Jul 2 2008, 05:28 PM)

Newton is kg*m/s^2.
So what is unit's of pressure? Anyway it's don't interesting to me what is units and bl bla bla. I want to know what is presure of single photon into say metal or into mirror. I know only that pressure into black matter is twice smaller than into mirror, becouse mirror reflecting and thus pressure is twice bigger...
so probably aceleration is measured in newons like 0.5*m*v^2, but this is job nad should be measured in joules. But say, that there flying proton with speed 1m/s and bouncing into mirror or metal and his momentum is given to object and thus there must be some pressure of proton and I want to compare this pressure with pressure of photon of any frenquency!!! So how to claculate proton pressure of not reletivistic speed and how to calculate photon pressure of any frenquency into say some matter which absorbing photon and proton. And by the way, is there is diferent in presure if pron is absorbed and if reflected?
excaza
Units should be interesting to you, if you could keep them straight you wouldn't look like such an idiot. Take a physics class.

In physics class there no any information about single photon pressure, but only about pressure of Sun light, you think it's helping me? Yes, helps, but very not much. Only can say, that this rpessure is very small like possible can be hf/c^2.

edit: here in textbook writen what sun light pressure is 4/10^8 N/m^2. Even 1mg have bigger presusre (~10 mN).
Enthalpy
A single photon has a momentum (not a pressure) of E/c.

Many photons per seconds, best measured by a power per surface unit Q, have an incoming pressure of Q/c. Double that pressure for a mirror, sum vectors if the mirror is tilted.

For Solar light at our distance from the Sun, 1350W/m2 push 4,5µPa.
DavidD
I will ask in over words: how much kinetic energy have one photon of any frenquency? Say proton kinetic energy is E=0.5*m*v^2, thus I think photon kinetic energy must be E/c^2=h*f/c^2. Am I right? Or such formula don't exist? But it would be little bit strange, becouse is possible to do such experiment by radiating say diferent wavelenght light on wire two plates, one mirror and one black. What is your answer?
dwk
A photon's energy is (by definition)

E = h f

(f is frequency in Hz, h is planck's constant)
Obviously you can't do (1/2)mv^2 since that equation only applies to particles with mass (i.e. fermions). Photons are not fermions. They are pure energy without mass.

Oh, and momentum has units of Newton-seconds (N.s). Pressure has units of Newtons/m^2
just to clarify.
DavidD
But if photon have pressure, thus it must have kinetic energy!

With every post DavidD plumbs the depths of stupidity and just when you think there's nothing more idiotic that can be said...

Of course water waves have mass. If they were massless they would travel at the speed of light!

Photons have kinetic energy because they have momentum. The photons KE is given by E = pc as you might expect. Remember that here p is not mc since the photon is massless, but it is p = h/λ so E = hc/λ

To talk about the pressure of a single photon is an exercise in futility because pressure is a statistical property of many particles. Single particles don't have a pressure any more than they have a temperature or entropy.

Thus I think that kinetic energy of single photon is E_k=h*f/c^2 and total energy of photon is E=E_0+E_k=h*f.

Your theory is completely and utterly wrong. Firstly a photon has no mass, hence, no rest energy. Secondly hf/c^2 doesn't have the dimensions of energy, so it can't be an energy. Thirdly, every experiment ever performed on the energy of electromagnetic waves contradicts you. Nice job.

lemme get this straight...

you say that photons can't have a lot of energy because they're ineffective at pushing matter

but then you say that photons must have a lot of energy because they power solar panels effectively

but then you say that E=hf is way too much energy for a photon, so you divide it by c^2 to make it smaller

but then you say that E=hf is only one component of the total energy of a photon.

PLEASE TELL ME THIS IS JUST A BAD DREAM!!!

I don't sure how to understand this, but only like rest mass... Think in this way, photon have vibration in two dimension like wave, this wave has energy and can hit in up and down and in straigt. Thus this hiting up and down is rest energy of photon E_0=h*f and this hiting in flying direction is kinetic energy of photon E_k=h*f/c^2. What is unclear?

Well DavidD, you do seem to think you know what you're talking about. If you want the scientific community to take you seriously though, you really should consider taking this to scientific publication.

PRL is a good place to start:
http://prl.aps.org/

DavidD
It's very strange that no such experiments to measure single photon pressure and thus - kinetic energy. Supose if you know how much arives photons in m^2 from Sun light and how much there is of them of diferent frenquency, then there is possible to calculate pressure of single photon and thus kinetic energy. Why such calculations wasn't made, probably becouse photons theory is incomplete like I now saying, that photons isn't particles, but only waves and that radiated energy of single atom can't be detected, becouse wave spreading and actualy there is many waves of many atoms sum one photon detection, but this one photon misleadingly interpetaed as photon colpase of single atom radiated wave.

Possible that imposible to calculate energy of single sphere kinetic energy, becouse we don't kow of how much spheres consist single proton or electron adn even photon and I am not sure if wave will be shorter than sphere radius, does wave will be able to trave or not. but this seems more like traveling then of single sphere than wave, but becouse of vibration of over sphere it can travel like wave and even possible, that each sphere is actualy represent wave.

Energy need proportional to relativistic mass. It's imposible to say how much waves or energy need to excide detector, becouse detector is not etalon and it counting diferent waves amplitudes and frenquencies. So if in supernonrelativistic speed need energy E_c, then in relativistic speed need E_c/(1-(v/c))^0.5, where c is not speed of light, but some constant wich due to hystorical reasons means speed of light in current understnading, but in my theory it's just some constant.
Of course you may say, why big explosion of galxies don't reaching with infinity speed detectors? But maybe exactly this is? Or maybe simply energy can be transfered only with waves after waves and need to wait very long untill it will induced be...!? thus in my theory energy don't comes from nothere and if there is anihilation, then there slowly produced many infinity fast waves series, like sinusoi or somthing, which traveling with infinity speed and untill all this sinusoide will not go through electrons and thus excide them, this electrons will not make photoefect. Thus anihilation can go with finity speed thus waves will be also with finity speed (give up ). But key point in my theory is that there no photons and waves I don't know now. Maybe my theory realy is a fake?

If you are smarter than I then please measure single photon pressuer and shut up!

Back to my theory. Okey, say, you win, mass and ligh can't travel with infinity speed. But in some one places time going slower than in over, becouse some places moving faster than over. What is my connection? From faster time going point radiated photons will must be seen very strongly for those who are in slower time position. But this don't hapening, becouse for exciding slower placed eyes say need more "photons" - waves. Becouse electrons are heavier and is harder to made photoefect. This all explains entanglement, what actualy more photons are radiated and they flying into one direction and into another and exciding both detectors if they going through polarizers... Part of waves reflecting from one polarizer with diferent amplitude and going faster to next polarizer untill measurment wasn't doen because of stoped slow time... That's all! Entanglement explained!
Now supose you saying, but it is possible for from faster point will radiate stronger waves amplitude resonated and from slower point it will be measured faster, but it's actualy isliusion and wrong, still will be measured slower, becouse all processes are heavier and going on slower and thus everything still will be measured slower. Just imagine what from fast point sended movie consist 25 frames per second (FPS) and you getting in slower "stoped" time 3 frames which are blured instead 1 frame then again 3 frames and it's waisted 6 frames normal and per 5 times you will get per each time 3 blured frames. So if time going on slowly then you will see slide show of blured slides (in one slide mixed 5 frames). But this mixed frames have still useful information and if they are radiated from the same stoped place then you will get pure one slide, which is mixed of 5 frames, but where 5 frames is the same or almost the same. This is principle of entanglement process, there going 5 photons and they are detected as 1 wave, but this 5 photons already doen they work by traveling through all possible chanels in "entangled" scheme... Thus there is like faster than light scheme, but this scheme naturaly comes from relativity raven than stupid many universes or bohemans or any back in time stupidnes...

In textbook says, that photon mass is E/c^2=h*f/c^2 and photon impulse is E/c=h*f/c. But what is photon kinetic energy due to it pressure is unknown

Also find, that photon giving his impulse to electrons and thus loosing energy and becoming of shorter wave (I wondering how quantized atom absorbing such waves). Thus it's explains why photons making photoefect and can "take" electrons from atom. I think photon impulse h*f/c possible is photon kinetic energy.

But on the oer hand photon kinetic energy possible to measure how long it interacting with particle in which he loosing his energy, so if particle lengh is 1/10^15, then need calculate how much time photon giving his impulse to particle.

Yes, becouse don't exist such thing like photon... And because you probably want to say, that those waves are absorbed, and each photon have pressure with kinetic energy E=h*f ? And only very small amount is absorbed? No... somthing wrong. Pressure must be and is according to textbook (of course single photon pressure can't be measured). Now there somthing very strange and even to my theory there is hard to explain... If waves always giving they kinetic energy to electrons, then in photoefect presure must be bigger than in over passing through experiment, but seems even in absorbtion experiments (wich are eqaul(?) to photefect) or in absorbtion there is only thermal energy given and not kinetic, becouse even reflected light have bigger presure than absorbed. So what is pressure of photon? Possible that most logical explanation of waves pressure remains my explanation, that phoefect energy and absorbtion is energy of vibration of waves and pressure is energy of flying direction center of wave. But still there need some formula to measure this energy of say photon... E_k=h*f/c^2, why not?

So you're admitting you don't know what pressure is?

I know what is pressure, and what doing it, but for to do it need energy, which can't be E=h*f. Thus need some different formula, which nobody know. Possible that E_k=h. But I am don't know, becouse there no in textbook about, which photons have bigger pressure shorter or longer or the same.
DavidD
Ok, how possible that this makes sense E_k=h*f/c (J*s/s/m*s)=h*f/c (J*s/m). Thus Joules*second/meter is formule of energy given by photon per second and photon flying through one meter. Ha? For example if photon flying through particles of long of one metter if they put closly together, then flying such meter in remirored directions (or many meters) one second then photon will give one joule of energy. Nice, isn't? Wehn photon is absorbed or reflected, then if absorbed it giving energy depending on wavelenght, bigger wave lenght, more "presure" energy. So possible that true formula is E_k=h/c (J*s*s/m), but no and any physics don't measure it

If you don't get Joules from your equation, it's not an equation for energy. It's really that simple.

They won't check it because THE EQUATION DOES NOT GIVE YOU AN ENERGY

J*s/m is NOT ENERGY, it's momentum. Learn physics.

No, the normal force will be 98 newtons. Pressure is not measured in newtons. Thank you for illustrating that you have no idea what pressure is.

You're doing research? Since when? All you've done so far is make up theories, refuse to provide any evidence or experimentation, and make up equations that aren't dimensionally consistent (that means WRONG). You don't know basic physics, you don't know quantum mechanics, yet you try to say they're wrong, and have deluded yourself into thinking you deserve a Nobel Prize.

I think, that if my model explaining entanglement with polarization or interference reflection, then I deserve nobel prize, but if it explaining only with relativity, that with hidden local variables (which need create, becouse in my relativistic model they possible), then I deserve only somthing smaller...
The key point of my relativistic theory is that particles not waves or if they are waves then they colapsing with some very small time dialtion, becouse time is like stoped and speed c can to arive of particle half splited even from very large distance (of course if this distance is very very big then possible that particle will stuck and sometimes after very long time will colapse in this place, but model, that particle can go very far is not realistic) and thus particle little bit tolate, but it's can be compensated with faster electron nature or this is not the big deal.

You should probably learn the physics and math you're dealing with before trying to use any of it to explain...anything. So far you've failed to apply your model to anything you've been asked to model. The logical conclusion is that you're full of sh*t.

Your model is useless. Current quantum mechanics can answer the questions you've been asked (with the exception of the Pioneer anomaly, but since you think your model is so much better, you should be able to explain it for us) your model can do jack sh*t.

You don't even know what pressure is or how to make dimensionally accurate equations (translation: That makes equations WRONG), yet you expect a nobel prize.

My model explaining all mysteries of quantum mechanic! Quantum mechanic says, that there everything is unclear and mystical, and my model says, taht we flying with 0.999999999999999999c speed and thus all then can be explained. Thus then quantum mechanic is pease of frogshit, because there no any mysteries and so on. There no need any many universe or any stupid boheman interpretation if you don't believe in magic...

Do you ever get tired of being wrong?

Data, statistical, and calculation errors were already analyzed and ruled out by scientists investigating the anomaly. 7 different analyses have shown the effect.

Must be tough knowing the "theory" you spent so much time working on is completely useless. Have you learned the difference between a Newton and a Pascal yet?
