Draw a diagram to show the reflection of a ray of light by a plane mirror. In the diagram, label the incident ray, the reflected ray, the normal, the angle of incidence and the angle of reflection.

Describe an experiment to verify the laws of reflection of light.

The diagram shows an incident ray AO and the reflected ray OB from a plane mirror. The angle AOB is 30°. Draw normal on the plane mirror at the point O and find:

(a) the angle of incidence

(b) the angle of reflection.

In the following diagrams, measure and write the angle of incidence and draw the reflected ray in each case.
