Question

While tracing the path of a ray of light passing through a rectangular glass slab measure angle of incidence angle of refraction?

Answer 1

sin angle i/sin angle r=constant

Answer 2

Answer:

1 ) .

Both angles are equal to each others i.e. ∠i = ∠e.

2 ) .

Angle of emergence also increases.

3 ) .

The light ray falls along the normal or the refractive index of the two optical media are  equal.
