Concept Explanation
 

Reflection of Light

Reflection is defined as the process of turning back of light in the same medium on striking the surface of the object. Almost every thing we see around us is due to the reflection of light falling on the objects. Generally, the objects do not have light of their own they are visible only when the light that comes from different sources like sun, light bulbs, fire etc, fall on the surface and is reflected back.

The process of reflection can be explained using the above experiment:

  • When light falls on a smooth surface, a part of it gets reflected as shown in figure. 
  • The ray AO is incident on the surface at point O and is then reflected. This ray OA is called as incident ray.
