Question

For the same angle of incidence the angle
of refraction in three different media A, B
and C are 30°, 45° and 60° respectively.
In which medium will the velocity of light
be minimum?​

Answer 1

Answer:

hope this will help you

Explanation:

Since, the angle of incidence is same and medium from which light is entering, we can draw a relation: Greater the angle, less is the density of the medium and hence greater is the velocity of light. Thus, velocity of light is maximum in the medium in which the angle of refraction is 40 degrees.
