A kaleidoscope is an optical device which creates colorful, beautiful patterns due to multiple reflections in plane mirrors.

It is an optical device to produce numerous patterns of images.


  • Explain that light travels in a straight path.
  • Explain how light can be reflected.

What’s Going On :

It is a cylinder with three plane mirrors and loose, coloured objects such as beads or pebbles and bits of glass. As the viewer looks into one end, light entering the other end creates a colourful pattern, due to multiple reflections of these objects in the mirrors.
