Question

The angle made by incident ray of light with the reflecting surface is called

A.)Glancing angle
B.)Angle of incidence
C.)Angle of deviation
D.)Angle of refraction

Answer 1

Hint- Light is known to behave in a very predictable manner. If it is found that a beam of light was entering and reflecting the flat mirror, the light’s behavior as it reflects would obey a law known as the law of reflection.

Complete step-by-step answer:

In the diagram, an incident ray (labeled I on the map) is considered to enter the mirror. A mirrored ray is the light ray that leaves this mirror ( indicated in the diagram). When the ray enters the mirror, a line may be traced perpendicularly to the mirror surface. This line is referred to as a standard line (in the diagram labeled). The usual row splits the angle of the incident ray into two different angles with the reflected light. The angle of the incident ray to the normal is known as the incidence angle. The angle of the reflection beam to the normal is known as the reflection angle.

Also, glancing angle of incidence is defined as the angle between the incident ray and the reflecting surface.

Hence correct option is A

Note- The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection. The light, sound and water waves are typical examples. The law of reflection says that the angle at which the wave covers the surface is the angle at which it is reflected to reflect a specular reflection.
