# NCERT Solutions Class 8 Science Solutions for Exercise in Chapter 16 - Light

Question 4 Exercise

Suppose you are in a dark room. Can you see objects in the room? Can you see objects outside the room? Explain.

If a person is inside the room where there is no light, it is then impossible to visualize the object inside the room but the object out of the room can be seen easily.

When light falls on eyes after reflecting from the object, it becomes visible. If the room is dark, then the object which is in the room reflects no light. Hence, the person is not able to see the objects in the room where there is no light.
