Question

Consider the path of a ray of light passing through a rectangular glass slab for different angles of incidence. (i) Which one is greater: angle of incidence or angle of refraction? (ii) What happens to the emergent angle on increasing the incident angle at air-glass interface? (iii) State the conditions when no refraction occurs

Answer 1

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.
