Refraction Through Lenses

Refraction Through Mirrors

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 the convex lens in front of the ray box. make sure the ray box's central ray of light is hitting the lens at a 90 degree angle.
3. Carefully trace the direction of the incoming and refracted rays
4. Repeat using the concave lens.

Results:

Findings: I found that convex lenses make rays of light diverge (move apart) and concave lenses make rays of light converge (come together)
