Speed of Light

Speed of Light

Aim: To investigate how light behaves when it hits a plane (flat mirror)

Equipment: Light box, Transformer, mirror and paper protractor / plastic protractor.

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 a plane mirror on the diagram of the protractor as described.

3. Vary the angle of incidence and record the angle of reflection in the results table.

Results: 

Angle of Incidence	Angle of Reflection
0°	0°
10°	10°
20°	20°
30°	30°
40°	40°
50°	50°
60°	60°
70°	70°
80°	80°
