Shadows

shadow is a space where light from a light source is blocked by an opaque object.

  • A shadow is formed when a part of light is blocked by the object. If all the light is blocked by an object, then there will not be any shadow.
  • Shape of the shadow is always similar to that of the object but the size varies.
  • Shadows of different types of objects may have similar shape as the amount of light they may be blocking is same.
  • Shadows cannot occur in dark rooms (due to absence of light) and full lit rooms with no objects (due to absence of opaque object).
  • A shadow is always obtained on a screen like walls, ground etc.

A shadow is always black or grey irrespective of the colour of the object
