Question

for the same angle of incidence in media A,B,C, the angle of refraction are 20 degree ,30 degree and 40 degree respectively . in th which medium will the velocity of light be maximum ? give reason in support of your answer

Answer 1

...............................

Answer 2

From Snell’s law

n = sin i /sin r = c/v

Since c and sin i are constant therefore sin r is directly proportional to v

Therefore velocity of light is maximum in medium C.

Glad To Help :D
