luminous - emits light e.g. the sun
non- luminous - does not emit light though will often reflect light e.g. the moon.

Is a mirror non-luminous and why?
Yes, a mirror is nonluminous. It does not emit light by itself, it only reflects light emitted by other things.
Is a volcano erupting luminous or non luminous?
It is luminous
Is the earth luminous or non-luminous?
The earth is Non-luminous.
Is table luminous or non luminous?
It's non-luminous
Are glow in the dark objects luminous or illuminated?
Luminous.
Can a flashlight be luminous and nonluminous?
Yes
What is luminouse and non-luminouse?
i think luminous means when something gives off light and non-luminous means when something does not give off light.
What does nonluminous body mean?
Having a non-luminous body means that it is not a see-through body. Many insects have a non-luminous body. Non-luminous body also means an object that cannot reflect light.
Is a mirror non-luminous and why?
Yes, a mirror is nonluminous. It does not emit light by itself, it only reflects light emitted by other things.
What happen if heat is applied mat the bottom of the test tube?
differentiate luminous flame from non-luminous flame
What is luminous flame and Explain why it takes a longer time to heat equal amount of water using a luminous flame?
yellow color in a luminous flame produces soot or carbon. carbon dioxide is present in the luminous flame but when its combined with oxygen the flame is nonluminous which is in a blue color. it takes a longer time because luminous flame is cooler than the nonluminous. I only know what luminous flame is. The inner part of luminous flame is blue while the outer part of the luminous flame is yellow. It is unsteady. Yeah. Carbon Dioxide is only present in the luminous flame. When oxygen is combined with the flame, the flame will become non- luminous which is inner and outer part are blue. Hmm. Actually luminous flame's hottest part is at the bottom while non- luminous flame hottest part is at the middle and the top. That's all i know. If i know more, i will update for you. Thank you!

Why the dominant color of a nonluminous flame on a Bunsen burner blue?
The dominant color of a nonluminous flame on a Bunsen burner is blue. Whereas, the dominant color of a luminous flame on a Bunsen burner is orange.
Is the temperature of a luminous flame greater or less than that of a nonluminous flame?
a non-luminous flame- when the air hole of the Bunsen Burner is open"when the air hole is open, more oxygen can enter the burner; therefore, hotter flame will be produced."its color is transparent or blueBlue flames are the hottest flamesa luminous flame is produced when the air hole is closed.."if the air hole is closed, oxygen cannot enter the burner; therefore, least hotter because the combustion is not fully complete with least oxygenA luminous flame has an outer of orange color and an inner of blue.Luminous flames emits more light than non-luminous flames.three things to produce flame1.fuel2.oxygen3.friction or source of sparkLuminous objects emit light. The sun is luminous; the moon is non-luminous.
Should a luminous or non luminous Bunsen flame be used for heating in the laboratory and why?
Non-luminous flame should be used for heating in the laboratory because the flame is steady and produce little or no soot.Non-luminous flame is very hot thus, it is recommendable to use for laboratory purposes.Luminous flame is unsteady while non-luminous flame is steady.Another reason of using non-luminous flame because the flame of non-luminous is blue, and not visible unlike the luminous flame which is yellow in colour and visible.
Is the temperature of a luminous flame greater ot less than that of a nonluminous flame?
The yellow color in a luminous flame is basically the black-body emission from hot particles of soot in the flame. they are hot, and they glow like the filament of a light bulb. In a blue flame, there are no particles of soot to give that incandescent radiation. Instead, the main color you see is blue emission from the high-energy C2 molecule.
What is the color of nonluminous object?
TRUE
Is this a correct definition If it cannot reflect light is it nonluminous. For instance fabric cannot reflect light but it does not emit its own light?
No, that is an incorrect definition. Luminous means creating its own light. Non-luminous just means not creating its own light. For instance the Moon is non-luminous. It *does* reflect light. It just does not create its own. Fabric also reflects light. It does not reflect it the same way a mirror does (mostly the light it reflects is scattered) but the fact that you can see the fabric even though it is not emitting light itself means it is reflecting light emitted from other objects. However, it is still non-luminous because it does not create its own light.
