LUWU Don Science.1)
2. A ray of light goes from Medium A to Medium B. The angle of incidence is 30° and the angle of
refraction is 45°. Find the ratio v /v., where v, is the speed of light in Medium A and v, is the
speed of light in Medium B.
A plane​

Answer 1

Answer:

c/v = 1/root 2

Explanation:

Let medium A speed of light be ( c )m / s

Let medium B speed be v m/s

sin i/ sin r = c / v

sin 30° /sin 45° = c / v

1/2 / 1/ root 2 =c /v

1/root 2 = c/v
