Fix a white sheet of paper on a drawing board or a table. Take a comb and close all its openings except one in the middle. You can use a strip of black paper for this purpose. Hold the comb perpendicular to the sheet of paper. Throw light from a torch through the opening of the comb from one side. With slight adjustment of the torch and the comb you will see a ray of light along the paper on the other side of the comb. Keep the comb and the torch steady. Place a strip of plane mirror in the path of the light ray. What do you observe?

Arrangement for showing reflection
It is observed that after striking the mirror, the ray of light is .
We can see the relationship between the angle of incidence and angles of reflection. Angles are the .
The angle of incidence is always the angle of reflection, this is the .
