Question

how an angle of deviation upon the refractive index of the medium. explain it briefly.
​

Answer 1

Answer:

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. Example: A prism has a refractive index 23 and refracting angle 90o.
