Question

For a light refracted by a prism angle of devitation​

Answer 1

Calculate angle of minimum deviation of light ray passing through prism - example. The Angle of Deviation is the angle equal to the difference between the angle of incidence and the angle of refraction of a ray of light passing through the surface between one medium and another of different refractive index.

Answer 2

Answer:

The angle of deviation of a ray of light in passing through a prism not only depends upon it's material but also upon the angle of incidence but in case of minimum angle of deviation in a prism, the angle of incidence is equal to angle of emergence. Hence, the correct option is A.
