What is a Shadow?
A shadow is a dark shape made when an object blocks light from the sun or a torch.

Shadows change size because of how close or far the light source is to the object blocking it.
Can we see a shadow in the dark?
No, we need light to make a shadow. In complete darkness, shadows cannot be formed.
Do all objects make the same kind of shadow?
No, solid objects make dark shadows, while transparent objects like glass let light pass through and do not make clear shadows.
