Question

Consider the path of a ray of light passing through a rectangular glass slab for different

angles of incidence.

a. Which one is greater: angle of incidence or angle of refraction?

b. What happens to the emergent angle on increasing the incident angle at air-glass

interface?

c. State the conditions when no refraction occurs.​

Explanation:

a)Angle of refraction is the measure of angle between the normal and the refracted ray. Overhear the light is passing through a rectangular glass slab which means the real flight travels from air to glass and in this case the angle of incidence will be greater than the angle of refraction.

b)For different angles of incidence, the lateral displacement will remain the same. The light will bend towards the normal when it travels from an optically rarer medium to an optically denser medium

c) in second condition .
