Question

Considering the same angle of incidence of 45°, the angle of refraction for three transparent media

P, Q, R are 30° , 35° 40° respectively. The speed of light will be maximum and minimum in

which of the above three media?​

Answer 1

Answer:

Proper algebra yields to the answer of 32.1 degrees for the angle of refraction.
