What is the difference between regular reflection of light and diffuse reflection of light? What type of reflection of light takes place from?
(a) A cinema screen
(b) A plane mirror
(c) A cardboard
(d) Still water surface of a lake
The difference between regular reflection of light and diffuse reflection of light is that in regular reflection, a parallel beam of incident light is reflected as a parallel beam only in one direction; while in diffuse reflection, a parallel beam of incident light is reflected in different directions.
(a) The type of reflection of light that takes place from a cinema screen is Regular reflection
(b) The type of reflection of light that takes place from a plane mirror is Regular reflection
(c) The type of reflection of light that takes place from a cardboard is diffuse reflection
(d) The type of reflection of light that takes place from still water surface of a lake is Regular reflection

Varun’s mom is finding it difficult to cook in the kitchen as there was power cut and she was complaining about it to Varun. He immediately took a plane mirror from his shelf made it stand against a wall such that sun’s rays were focused into the kitchen directly on the cook top, due to the reflection of the mirror. There was some light now and his mother was able to finish her work.
