Aim: To show the reflection of light from a plane mirror.
Materials Required: Protractor, plane mirror, laser light, white sheet and pencil.
Procedure:
1. Place a plane mirror on a plane white sheet.
2. Draw a line at right angle ( normal ) to the edge of the mirror.
3. Take an incident ray at 30° angle and make its path by placing pins.
4. Throw the laser light beam along the incident ray path.
5. Make the reflected ray path through pins.
6. Remove all the pins and draw the line along the path.
Observation: The angle of incident is equal to the angle of reflection.
