Question

In case of refraction, when the light passes from rarer to

a denser medium, if the angle of incident is 65o and angle of

refraction is 25o, then the deviation of angle would be​

Answer 1

Answer:

Explanation:

Laws of refraction;-

The incident ray,the refracted ray and the normal to the refracting surface at the point of incidence lie in the same plane.

For a given pair of media and for a given colour of light the ration between the sine of angle of incidence to the sine of refraction is a constant.This constant is known as refractive index of the second medium with respect to the first medium.

When a ray of light passes through a glass slab, ∠i,∠r and the normal all lie in the same plane.

When a ray of light passes from one medium to another, here from air to glass or glass to air, the ratio

=constant.
