Project
Repeat Activity 11.4, but this time cover the face of the torch with a coloured transparent paper and observe the colour of the shadow. Repeat this using transparent paper of different colours. Report your conclusions. Also, find out what happens when two or more mirrors are kept at an angle or parallel to each other, and whether a small mirror can form an image of a large object.

Key Points
Coloured light changes the lit area, and more mirrors make more images.
Key Points
- Cover the torch with coloured transparent paper and watch the shadow.
- The shadow itself stays dark, but the lit area takes the colour.
- Try different coloured papers and note what you see.
- Two mirrors at an angle form many images of one object.
- A small mirror can still show parts of a large object.
Colour changes the lit area, and angled mirrors multiply the images.
