Investigating the Laws of Reflection

Today in Science we did a practical about lights and reflections.

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

Method:

1. Collect a ray of box, power supply, and single-slit ray slide from your teacher, and set them up to reduce 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 of the table.

Results:

0 degrees = 0 degrees
10 degrees= 10 degrees
20 degrees= 20 degrees
30 degrees= 30 degrees
40 degrees= 40 degrees
50 degrees= 50 degrees
60 degrees= 60 degrees
70 degrees= 70 degrees
80 degrees= 80 degrees




The angle of reflection was the same as the angle of incidence because the mirror is flat
