Question

What is the difference between the glancing angle of reflection of a light ray and the angle of reflection of a light ray?

Answer 1

Answer:  

The angle between an incident beam (on a plane of surface) and the surface is called the glancing angle of incidence.

Simply it is the angle made by the incident light with the plane of the surface (on which the light is incident)

The angle between a surface and a beam of particles or radiation reflected from it is called glancing angle of reflection. It is the complement of the angle of reflection is called the glancing angle of reflection.

Simply it is the angle made by the reflected light with the plane of the surface (from which the light is reflected)

Answer 2

Answer:

Explanation:

the angle between normal and incident ray is called angle of incidence but the angle between surface and  incident ray is called glancing angle of incidence.
