Detailed Solution

The above statement is False.
A light source is defined as an object which can emit radiations of light or light energy radiations into the environment. Sun, stars, lightning and fireflies are natural sources of light. A natural light source produces naturally without human involvement and is also called a luminous object. And sources of light made up by humans or artificially are called artificial sources of light, like bulbs, oil lamps etc., and properties of an artificial source of light, like the speed of propagation, brightness, contrast, etc., can be changed externally. Or artificial objects which emit light, like electric bulbs, are called artificial luminous objects, and objects like the sun and fireflies are natural luminous objects which emit light.
The correct statement would be that an electric bulb is an artificial luminous object, and the sun is a natural luminous object.
