Dispersion

The dispersion of light is briefly discussed. Then the refraction of white light through a prism is demonstrated using rays of light on a chalkboard. Next, a narrow beam of white light from a slide projector is allowed to pass through a small glass prism and the refracted beams of different colors are observed on a screen.
Equipment:
- Power supply
- Connecting wires
- Triangular transparent plastic prism
- Rectangular transparent plastic block
- Glass prism mounted on stand
- Slide projector as light source
- Screen
