Question

For the same angle of incidence in media A, B and C the angles of refractive 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 a because more velocity less angle of reflection

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
