Question

Define the angle of reflection.

Answer 1

Answer:

When a ray of light interest at a point of a mirror and reflect in any direction by forming an angle, the angle formed by the reflected ray is called angle of reflection.

Here, angle R = angle of reflection

Answer 2

Angle of reflection

Explanation:

The ray of light which is sent back by the mirror from the point of incidence is called reflected ray. The angle between the reflected ray and the perpendicular or normal to the surface is the angle of reflection. It is represented by the symbol r.

i stands for the angle of incidence, which is the angle between the incident ray and the normal.

As per the laws of reflection, the angle incidence = angle of reflection.

∠i = ∠r
