Bounce between different objects
Explanation:
Light probably will bounce off of objects or it might go through, i think it depends on what object and what material.
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. no light falls on the surface of objects and we do not see them. This is why we cannot see the objects in a dark room.
