When light falls on objects, it bounces off from the surface of the objects and then enters our eyes. Ou eyes sense it and send messages to the brain. It's finally, the brain that sees the objects, and the eye are an aid in seeing. The objects that emit light are called sources of light, e.g the Sun, stars, torch etc. When light falls on any object, it bounces off from the surface of the object in all directions. This called scattering of light. The objects which emit light on their own are called luminous objects. These can be natural or artificial The sun and the stars are natural luminous objects, while electric bulbs and burning candles are arti Luminous objects. The objects which do not produce light on their own are called non-luminous object e.g. table, chair, planets, moon, etc. These objects become visible only when light falls on them and reflected by them.
