A blue colored flame which produces very little light is called nonlunminous flame. In other words when a fuel undergoes complete combustion it is non luminous flame.
A yeelow flame which produces heat and light is called luminous flame.In this the fuel undegoes partial combustion.

preetijain46471: Wrong answer
preetijain46471: My question is just for example
rahulgupta100008: luminous zone:-

the wax vapours do not burn completely as the supply of oxygen is inadequate.the carbon particles glow emitting a yellow light.it is the middle zone of the flame.

non-luminous zone:-

because of adequate supply of oxygen,complete combustion occurs.the flame appears blue.it is the outermost zone of the flame
rahulgupta100008: ok i apologize
preetijain46471: Wrong
rahulgupta100008: i am really apologize for my answer
rahulgupta100008: Thus luminous objects are responsible for our vision. Example - Example: Lighted candle, torch bulb, the sun and stars. Sun also emits light as a result of fusion of Hydrogen atoms. Hence they are considered as Luminous objects.
rahulgupta100008: Objects that emit light on their own are called luminous objects. Best examples of luminous objects are the sun, stars, light bulb etc. Objects that do not reflect light are known as non luminous objects. Examples of non luminous objects are wood, plastics, metalsetc.

luminous-1.bunsen burner, 2 oil lamps
non lum-Non-luminous flames are the ones that burn blue. These flames have access to as much oxygen as they could possibly use, so they can burn very efficiently. All of the carbon that gets used can be turned into CO2, so there's actually no soot.

preetijain46471: Love you yar you gave me the correct Otherwise I am just getting tired of others answer
DSamrat: thanks dear..chilax.. it happens by mistake..let it go..ignore
rahulgupta100008: i think this is wrong
