About Reflection

To see an object light must come from the object and go into our eyes. Most objects do not make their own light, so instead they reflect the light that is made by something else, like the sun or a light bulb.

In a dark room you cannot see any objects because there is no light to reflect off the objects.

When you turn on a light bulb in a dark room the light travels from the light bulb to the objects in the room. The light then reflects off the objects and goes into your eyes. That is how we can see the objects.
