Refraction through lenses
Aim:
To investigate how different types of lenses refract light.
Method:
1. Set up a ray box, triple-slit ray slide and power supply
2. Place the convex lens in the 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 the concave lens.
