Question

What do you understand by reflection of light? Explain the phenomenon with the help of an experiment.

Answer 1

When light rays bounce off the surface of an object, the phenomenon is called reflection of light.
Experiment: Request one of your friends to hold a mirror in his/her hand at one corner of a darkroom. You stand at another corner with a torch in your hand. Switch on the torch and direct its light beam onto the mirror held by your friend.
You can see a patch of light on the other side. Adjust the direction of the torch so that the patch of light falls on another friend standing in the room. This happens due to the reflection of light from the mirror.
