There are two basic types of light sources: Incandescence and Luminescence.

What is the natural source of light?

A natural source of light refers to a light produced naturally without any involvement of humans. Natural sources of light can either be obtained from an object or a living species. Examples of natural light sources are Sun, stars, Lightning, Jellyfish, Fireflies, Glowworms, Bush fires, Angler fish, etc.
