Light boxes.
We have set up a light box. The light box takes a 12v battery to work. All the light box does is project light. The light bulb inside gets turned on. We have different things that we cun put into slots that make the light get projected different.
----------------------------------------------------------------------------------------------------------------------------------
Aim: To investigate how light is affected by changing the substance it is travelling through.
Equipment: Ray box, power source, flass or perspex block, single slit ray slide.

Angle of incidence 10 angle of refractation is 8
Angle of incidence 20 of refraction is 15
Angle of incidence 30 of refraction is 20
Angle of incidence 40 of refraction is 20

Aim: To investigate how different types of lenses refract light.
Equipment: Triple-slit ray slide, Power supply, a concave lens and a convex lens.
Method:
1 set up a ray box, triple-slit ray slide and power supply.
2: Place he convex lens in thew space below. Place the ray box at the top of the page and shine the three rays of light at the lens. make sure the central light ray hits the lens at 90 degrees as indicated in the diagram.
3: Carefully trace the direction of the incoming and refracted rays.
4: Repeat using thre concave lens.
