Question

for the same angle of incidence in media a,b and c, the angles of refraction are 200 , 300 and 400 respectively. in which medium will the velocity of light be maximum? give reason in support of your answer

Answer 1

40 degree not sure about it please see it once

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
