Speed of Light

 

Speed of light

Aim: 

To investigate how light behaves when it hits a plane(flat).

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

Result:

Angle of incidence	Angle of reflection
0°	0°
10°	10°
20°	20°
30°	30°
40°	40°
50°	50°
60°	60°
70°	70°
80°	80°
