Light Moves the Shadow

A light source makes a shadow when an object blocks it. If the light is high or close, the shadow becomes shorter or longer and points in a different direction.

In the picture

  1. The tall lamp is the high light source.
  2. The toy figure blocks the light.
  3. The long shadow stretches far to the right.
  4. The short shadow stays close to the left.

Examples

  • At sunset, your shadow gets longer and points a different way.
  • A ceiling light makes a short shadow under a chair.
