Ch – 11 Lights, Shadows And Reflections

  • Objects like the sun that give out or emit light of their own are called luminous objects.
  • Objects like moon that do not give out or emit light are called non-luminous objects.
  • If an object allows light to pass through it, then it is transparent object.

  • If an object does not allow light to pass through it, then it is opaque object.
  • If an object allows only partial light to pass through it, then it is translucent object.
  • The dark patch formed, when an opaque object opposes the passing of light, is known as shadow.

  • Three things needed to form a shadow are: an opaque object, an opaque screen and a source of light.
