Question

She has gone to picture hall to watch a movie and she notices that the screen of cinema is very rough and off white colour she tries to relate this with the concepts of light taught by her teacher in classroom .Help her to find the answer. PLEASE SOME ONE ANSWER ME..............​

Answer 1

Explanation:

its is because on rough screen, reflection takes place more and it can reach out more audiences.

And the white colour is the best colour which reflects the most of the light that falls on it.

Both combined for mostly one purpose that is for better reflection of light that falls on it so that it covers entire movie hall.
