Which light rays undergoes two internal reflection inside a raindrop, which of the rainbow is formed?

A light ray is incident on a transparent sphere of index = sqrt(2) , at an angle of incidence = 45^(@) , What is the deviation of a tiny fraction of the ray, which enters the sphere, undergoes two internal reflections and then refracts out into air?

In internal reflection light reflects from which medium to which medium?

Total internal reflection is possible when light rays travel

Based on refraction and total internal reflection explain the formation of rainbow.

The primary rainbow is due to _______ internal reflection inside droplet and two refractions.

A ray of light from a sodium lamp undergoes total internal reflection.The critical angle will be smallest,when it travels from

When light ray travels from ...... then total internal reflection is possible.
