Question

a ray of light is inclined at an angle of 30 on one top surface of a parallel sided glass of refractive index 1.5 the ray finally emerges from the law surface what is the angular of deviation of the emerged ray

Answer 1

Answer 2

Answer:

Correct option is

B

1/sini

Applying Snell's law at glass-water surface,

gwμ=sinisinr=wμgμ...(i)

Applying Snell's law at water-air surface,

waμ=sinrsin90∘=aμwμ...(ii)

Multiplying (i) and (ii),

aμgμ=sini1 ⇒gμ=sini1.
