Question

A ray of light is incident at an angle i on the surface of glass slab. If its angle of refraction inside the glass block is r, then find the relation between i and r assuming that light enters from air and emerges into air.​

Answer 1

Answer:

the refractive index = sinI/sinR... by Snell's law

Answer 2

Answer:

The relation is refraction

Explanation:

SO, as we know that when a ray of light passes through rarer medium to denser medium it bends towards the normal because the speed of light in denser medium is slow than that of in rarer medium.

Now when the ray of light passes through denser medium to rarer medium it moves away from the normal so In that case the the light ray is called emergent ray. And the distance between the incident ray and emergent is called lateral displacement..
