The moon, itself doesn't so much "give off light" as it reflects light from the sun. On those occasions the moon is positioned between the sun and the earth, we get an eclipse as the moon is blocking the sun for a short period of time.
photosphere
The part of an incandescent light bulb that gets hot and produces the light is called the filament.
There is actually no certain 'part' of the atom that gives off light. As you know, light is made out of photons. Photons are given off by the atom when it releases energy to get rid of the energy. I hope this helps!
It's the solar energy which is emitted as "visible light", sometimes called the "optical region" of the spectrum. Some we can see, some we cannot (the some we can't see are things like X-rays).
In an incandescent light bulb the wire that gives off the light is called the Filament.
The sun gives off light through a process called nuclear fusion in its core. This light then travels through space and reaches Earth, where some of it is reflected off surfaces like clouds, water, and sand.
The outer part of the Sun, that emits the light we see, is called the photosphere.
How about, it gives off light.
The amount of light a star gives off is the intensity or luminosity. Absolute Magnitude measures the amount of light given off.
The mineral that gives of ultraviolet light is Quratz
The photosphere gives off heat and visible light.
Bioluminescence - if it gives of visible light. However heat is also light and metabolism itself therefore gives off light, but you can not see it because it is infrared light.
