What is Light?
Light can be defined as the form of energy which helps us in seeing objects. Basically, when the light rays fall on an object, some of the rays are reflected in our eyes and it makes us see an object. Based on the emission of lights, objects are divided into luminous and non-luminous objects.
Luminous Object: The objects that produce light are called the luminous objects. The Sun, bulb, tube light, torch lighted candle are examples of luminous objects.
Non-luminous object: The objects that do not produce light are called the non-luminous object. Moon is an example of non-luminous objects.
