∙ 14y agoa 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 blue
Blue flames are the hottest flames
a 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 oxygen
A 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 flame
1.fuel
2.oxygen
3.friction or source of spark
Luminous objects emit light. The sun is luminous; the moon is non-luminous.

∙ 13y agohmm, the main difference... one produces *visible* light, the other does not :P
A non-luminous flame is blue in color, hardly visible, less wavy and hotter than a luminous flame. A luminous flame is not as hot, visible, orange in color, and wavy. A luminous flame is most used in experiments because it is less wavy and you have more control of it...
The temperature of a luminous flame is generally lower than that of a nonluminous flame. This is because in a luminous flame, some of the heat produced is emitted as visible light, whereas in a nonluminous flame, more of the heat is retained as thermal energy.

∙ 13y agoA non-luminous flame is normally used in laboratories, and is blue in color. That is because the flame is cooler, and does not produce soot. The luminous flame is way hotter, and is yellow in color. The luminous flame contains carbon dioxide, while the non-luminous flame contains oxygen.

∙ 14y agobecause luminous object loss some energy in the form of flame

complete burning, while the luminous part is tiny carbon particles which
did not burn

Non-luminous flame
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.
A luminous flame is one that emits light due to incomplete combustion of fuel. It takes longer to heat an equal amount of water using a luminous flame because a significant amount of heat energy is lost as light instead of being transferred to the water. This means less heat is available to raise the temperature of the water, resulting in a longer heating time.
A luminous flame produces soot, which can contaminate the experiment or react with chemicals being used. In addition, the temperature of a luminous flame is not as high or consistent as a non-luminous flame, making it less suitable for precise heating applications in a laboratory setting.
Non luminous zone is the zone of a flame which is also the hottest zone of the flame as it is mostly in contact with oxygen. It is also called invisible zone.
Turning a luminous flame to a non-luminous flame when not in use conserves fuel because non-luminous flames burn more efficiently. A non-luminous flame produces less soot and smoke, making it safer and better for indoor air quality.
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.
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.

For a Bunsen burner the lowest temperature is in the extreme lower part of the flame.

blue flame is more important for laboratory procedures since it's also known as the reducing zone of the flame in which the tip of the blue flame has the highest temperature. and thank you , a Dental student ;D
-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.
The degree of a luminous flame is 100 degree .
