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

in 200 your velocity of will be maximum because the least the angle r the more velocity of light is produced

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
