Light is a form of energy which is responsible for the sense of sight.It enables to see things around us.
- Light enables us to see every object around us like trees, vehicles, houses, people, etc.
- At night due to the absence of sunlight, it becomes dark, which reduces our visibility.
- Objects that emit light are called Luminous Objectslike sun, bulb, tubelight.
- Any non-light emitting object is visible when light from a luminous source falls on that object and then reaches our eye.These objects are called Non-Luminous Objects like trees, animals, shoe, moon (it seems glowing because of sun’s light falling on it) etc.
