Question

give reason We are not able to see in dark room.​

Answer 1

Answer:

We see an object when light falls on it and gets reflected from its surface and enters our eyes. In a dark room, there is no source of light. Thus, no light falls on the surface of objects and hence we do not see them. This is why we cannot see the objects in a dark room.

Answer 2

The main problem is that there is no light in the dark and we need light to see. Human eyes are adapted to see best in the daytime. We sleep at night so unlike nocturnal animals our eyes don't have the enhancements to capture as much light as possible in the dark.
