Question

When white light is incident on a set of glass slabs what happens to the emegent ray and what is the angle of refraction

Answer 1

Answer:

Explanation:

bonjour

The angle of incidence on the first surface { from air to glass} be i and the angle of refraction at the first surface be r. Since the surfaces are parallel the ray inside the glass falls at the other surface at angle r and therefore the ray emerges at angle i that is the angle of incidence.
