Question

State the laws of reflection .Draw a diagram to show incident and reflected rays.​

Answer 1

Answer:

Two laws of reflection are as follows:

1. Angle of incidence and angle of reflection is always equal.

2. The incident ray, the normal at the point of incidence and the reflected ray lie on the same plane.

Answer 2

Answer:

Explanation:

First, we consider reflection, as shown in the diagram below for a light wave striking a surface. We identify the incoming ray as the incident ray and the outgoing ray as the reflected ray. Concomitantly, the angleθi​  that the incoming ray makes with a line (dashed in the diagram) normal to the surface is called the angle of incidence. The angle θr​  for the reflected ray is called the angle of reflect.

The law of reflection states that the angle of incidence is equal to the angle of reflection, or, stated mathematically.

And also the incident ray, the reflected ray, and the normal to the surface of the mirror all lie in the same plane
