Question

A ray of light is travelling in a direction perpendicular to the surface of a glass slab. The ray of light: (A) is refracted towards the normal (B) is refracted away from the normal (C) is refracted along the normal (D) does not reflect at all​

Answer 1

Explanation:

When a incident ray of light it is falling perpendicular to the air glass interface it means that the angle of incidence is 0°. Applying Snell's Law at that interface: This means that the incident ray does not undergo any refraction and hence does not undergo any deviation.

Answer 2

Answer:

d.does not reflect at all

Explanation:

A ray of light is Travelling in a direction perpendicular to the boundary of a parallel glass slab the ray of light does not reflect at all..
