what is luminous, non luminous and illuminous source of light.
Every 75-76 years. It last appeared in view on February 9th 1986 and will not be visible again until July 28th 2061
Non-luminous. Objects which produce light of their own or give out or emit their own light are called luminous objects. Objects which do not produce light of their own, on the other hand, are called non-luminous objects. Luminous objects are objects like stars, sun and other celestial bodies which give out their own light. Objects surrounding us are not such light emitting objects. Therefore, we are surrounded by non-luminous objects.
by reflecting the light energy
Luminous objects are those which can produce or give out light of their own, while non-luminous objects cannot produce or give out their own light. Some examples of luminous objects would be the sun, stars, fireflies, glowworms and some deep sea fish Some examples of non-luminous objects would be the planets Mercury, Venus, Earth, Mars,Jupiter, Saturn, Uranus, Neptune and also Moons.
We expect Halley's Comet in 2061.

About every 76 years, for a few weeks on each return.

A luminous flame flickers while a non-luminous flame remains steady.
-A non-luminous flame is when the air hole of the Bunsen burner is closed but a luminous flame is produced when the air hole is opened.-A luminous flame has an outer of orange colour and an inner of blue. A non-luminous flame has an outer of blue and an inner of orange.-A luminous flame produces soot while a non-luminous does not produce soot.-A luminous flame is weak and unsteady. A non-luminous flame is strong and steady.-A non-luminous flame is very hot while a luminous flame is not too hot.
