Question

Why can't we see in complete dark room?

Answer 1

HEY MATE HERE IS YOUR ANSWER.


This is because there is no light present in the dark room. When we seethrough the glass window we can seethe things outside the window, this isalso due to the presence of light. Some objects allow the light to pass through them while some objects don't and in some objects, light passes partially through them.

Answer 2

light comes from an object enters the eye through the cornea and pupil. the light sensitive cells of the retina get activated when light falls on them. they then generate electrical signals. these electrical signals are sent to the brain through optic nerve. the brain interprets these signals in such a way that we can see a object.
so if no light will be there we can't see
