Refraction - Bending Light

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

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 ray of light.

1.  Place the glass block in the shaded area below

2. Place your ray box  at the top of the page and shine beam so it travels along the 10 degree line to the centre of the protractor (this is your angle of incidence)

3. Read the angle the light leaves the glass block at (this is your angle of reflection)

4. Continue the investigation so you can complete the table opposite

Angle of Incidence	Angle of Refraction
10 degrees	7 degrees
20 degrees	17 degrees
30 degrees	27 degrees
40 degrees	37 degrees

It depends where you put the glass block for your results 

Part 2

1. Place the glass block in the shaded area below



2. place the ray box at the top of the page and shine the beam so it travels along the 10 degree line to the centre of the protractor (this is your angle of incidence) 

3. Read the angle the light leaves the glass block at (this is your angle of refraction)

4. Continue the investigation so you can complete the table below

Angle of Incidence	Angle of Refraction
10 degrees	6 degrees
20 degrees	14 degrees
30 degrees	28 degrees
40 degrees	36 degrees
