4.5 Shadows

The objects that we see around us in our daily life can be classified into:
  • Transparent objects
  • Translucent objects
  • Opaque Objects
Transparent objects: These objects allow the light to pass through them.
Examples: glass, polythene ,etc.

Translucent objects: These objects allow the light to pass through them partially.
Examples: butter paper, very thin piece of cloth, etc.

Opaque bodies: These objects do not allow light to pass through them completely.
Examples: piece of wood, stone, etc.

Shadows: Shadows are formed when light falls on an opaque body. When sunlight falls directly on us that is during afternoons, we find our shadows shorter. As the noon passes we find the shadows elongated.
