Answer 1

YES

Anything that emits light or reflects it can be called as a "Light Source".

However, They are divided in 2 different Categories such as :-

• Primary Light Sources - are sources of Light which emit light on their own.

          For Example :- Bulb, Stars(like sun), Candle etc.

• Secondary Light Source - are sources of Light which don't have Light of their own but reflect Light of a Primary Light Source.

         For Example :- Moon, Planets(like Earth), and every other object                       (Including us) that reflects light.
