Science - Light energy ( Refraction)

Aim: To investigate how light is affected by changing the substance it is travelling through.

Equipment: Ray box, power source, glass or perspex block, single-slit ray slide.

Method: Collect the equipment from your teacher, and set them up to produce a single beam of light.

1. Place the glass block in the shaded area below.
2. Place your ray box at the top of the pages and shine the beam so it travels along the 10-degree line to the centre of the protractor (this is your angle of incidence, i degree)
3. Read the angle the light leaves the glass block at (this is your angle of reflection r degree)
4. Continue the investigation so you can complete the table opposite.

Result:
