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.

∙ 6y agoThe Moon and the planets are non-luminous, as do not produce light, but reflect the light back from our Sun, which is a luminous source.

The planets aren't luminous but the light reflects on the sun so we can see them.

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.
How are planets different from satellites?
simple! planets are huge or normally bigger than satellites in terms of mass, area and size. planets normally have a atmosphere like the earth. planets revolve around the sun whereas satellites revolve around the planet. both of them are non luminous object which means they reflect the light from the sun. satellites are usually fragments of a planet when it was forming.
Definition of luminous and non-luminous sources of light?
what is luminous, non luminous and illuminous source of light.
What is luminous mean?
ANSWER:Luminous could also mean 'full of light or illuminated'. For example: luminous hands of a clock. Here, luminous denotes shiny or that give light. In the example: luminous room; luminous indicates well-lighted. Something that is clear or easy to understand is also termed luminous. Fro example: luminous prose or luminous theory. Luminous could also mean inspiring, intelligent, or enlightened.
Is hally's comet luminous or non luminous?
Yes it is
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 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?

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.
