Light
- Light is a form of energy. It enables us to see things around us.
- We cannot see any object in the darkness. To make it visible we need a source of light.
- During the day time, we can see an object because of the sun’s natural light.
- At night we can see with the help of artificial lights like bulbs, LED etc.
- Objects that radiate light on their own are called luminous objects. Such as sun, tube light, bulb etc.
- Objects that do not emit light on their own and require a source of light to become visible are called non-luminous objects. Such as cars, buildings, animals, trees etc.
