fire
A flashlight is luminous when it is turned on and emitting light. It is non-luminous when it is turned off and not emitting any light. So, a flashlight can be both luminous and non-luminous at different times depending on its operational state.
A wood fire is considered a luminous object because it emits light as a result of the combustion process. The flames produce visible light due to the heat causing gases and particles to glow. This characteristic distinguishes it from non-luminous objects, which do not emit their own light.
It's non-luminous
-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.
A TV, when it's on and showing an image is luminous. When it's off, it's non luminous.
The non-luminous fire exist when there is a complete combustion or complete burning process. It happens when there is more than the enough oxygen in the surroundings or in the place where the process will happen.
It is luminous
The hottest part of a fire is called the flame. Flames are the visible, luminous gas that is generated by the combustion process, and they represent the most intense heat and energy.
If the bulb is switched off, then we would call it non-luminous.
the types of non-luminous are bulb,candles ect
