A prism is a transparent solid block with a triangular base.
About Prisms
- Prisms show how white light is made of many different colours.
- The different colours all refract by a different amount, causing them to split.
When white light enters a prism it is split into a spectrum of 7 colours:
- Red
- Orange
- Yellow
- Green
- Blue
- Indigo
- Violet
