Finding:
The angle of incidence is the same as the angle of reflection.
Aim:
To investigate how light behaves when it hits a plane (flat) mirror.
Method:
1. Collect a ray box power supply and single-slit ray slide from your teacher, and set them up to produce a single beam of light.
2. Place the plane mirror on the diagram of the protractor as described below.
3. Vary the angle of incidence and record the angle of reflection in the results table.
