What is reflection? Explain with a diagram.

Class: Class 7 Subject: Science Topic: Basic concepts of Science

Reflection is the bouncing back of light when it hits a smooth surface. Instead of passing through or being absorbed, the light rays change direction and return from the surface.
When light bounces off a surface, it is called reflection.

When light rays strike a smooth, shiny surface (like a mirror), they reflect off at the same angle at which they hit the surface.

The angle at which the light hits the surface is called the angle of incidence.

The angle at which the light bounces off is called the angle of reflection.


Laws of reflection:

·         Angle of incidence = angle of reflection

·         Incident ray, reflected ray, and normal lie in the same plane
