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

Solution
Verified by Toppr

#### 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.

Does reflection of sound also undergoes the laws of reflection.
Laws of reflection state s that incident ray normalray reflected ray and emergent ray will lie in a same plane ,2. Incident ray is equal to reflected ray.and this is true in reflection of light .is it relative to reflection of sound?
