1.in an intrfrnce expmnt. wit monochromatic light of wavlngth 6000 AU only 50 fringes are observable.estimate d coherence of d source.
2.show a circularly polarised lght is eqvlnt to 2 mutually perpendicular plane polarised lt wit a phase diff of pie/2.
3.fringes of equal inclination are formed with a 2mm thck plnpll glass plate of n=1.50.how many fringes are formed entirely ? w=6000 AU
4.wht will b the phase diff in radians betwn 2 points 90cm apart, measured along the wavetrain y=2sin7pie(x-24t) ?

1.in an interference expmnt. wit monochromatic light of wavelngth 6000 AU only 50 fringes are observable.estimate d coherence of d source.
2.show a circularly polarised lght is eqvlnt to 2 mutually perpendicular plane polarised lt wit a phase diff of pie/2.
3.fringes of equal inclination are formed with a 2mm thick plane parall glass plate of n=1.50.how many fringes are formed entirely ? w=6000 AU
4.what will b the phase diff in radians between 2 points 90cm apart, measured along the wavetrain y=2sin7pie(x-24t) ?
5.what is the resultant intensity when 2 beams of incoherent light is superposed ?
