The candle has 4 zones:
Blue zone
Dark inner zone
luminous zone
non-luminous zone
The light from a candle flame primarily comes from the outer zone, known as the luminous zone or outer envelope. In this region, the temperature is high enough for incomplete combustion to occur, producing incandescent soot particles that emit visible light. The inner zone, or non-luminous zone, primarily produces heat and is less bright due to more complete combustion.
The various zones of a candle flame are the dark zone, the blue zone (inner cone), the luminous zone (middle zone), and the non-luminous zone (outer zone). In the dark zone, the wick is vaporized and breaks down into fuel molecules. The blue zone is where complete combustion occurs due to a sufficient oxygen supply, while the luminous zone emits light due to incomplete combustion of fuel. The non-luminous zone consists of unburned fuel and soot particles.

The radiation zone is a region in the interior of a star where energy is transported outward by electromagnetic radiation, primarily in the form of photons. In this zone, energy is carried through the star's layers by the absorption and re-emission of photons. The radiation zone is located between the core and the convection zone of a star.
The three main parts of the Sun are the core, radiative zone, and convective zone. The core is where nuclear fusion occurs, producing the Sun's energy. The radiative zone is where energy is transported by electromagnetic radiation, and the convective zone is where energy is transported by convection currents.
partial combustion takes place here and wax vapour start burning with a yellowwish flame . this region of candle flame is moderately hot. so it is called as the luminous zone
Because it is the hottest zone of a candle flame.
The two most polluting zones of a candle flame are the bright yellow outer zone, which contains unburned soot particles, and the dark zone close to the wick, which contains partially burned carbon compounds. These zones contribute to the production of pollutants such as carbon monoxide and particulate matter.
The dark zone in the candle flame, also known as the zone of no combustion, is where vaporized wax is breaking down into hydrogen and carbon, but there is insufficient oxygen for complete combustion to occur. This area appears dark because there is no visible flame due to the lack of oxygen.
These are the 4 zones of a candle flame from outermost to innermost A Non luminous zone . or zone of complete combustion b. Luminous zone or zone of incomplete combustion c. Dark zone or zone of no combustion d. Blue zone
when a candle is lighted ; this is what happens : the solid wax melts and rises up the wick. The wax vapours react with oxygen to burn as a flame. The candle starts melting. This is a physical change. while observing the candle flame we see that the candle has 3 zones. Non - Luminous zone is the innermost zone. It appears as a dark zone and is the coldest part of the candle flame due to less oxygen. Then comes the Luminous zone , it is yellow and opaque. The glowing of carbon particles cause the flame to look yellow and emit light. Then , Invisible zone - it is the outermost zone of the candle flame. it is the hottest zone and cannot be seen with naked eye. Combustion reaction comes to completion here and carbon changes into carbon dioxide.
The candle flame has 4 zones from innermost to outermost: 1)Blue zone: It is near the base of the flame. Here the fresh air rapidly mixes with was vapour formed from the molten wax.A part of wax vapour completely burns and gives rise to blue flame. 2)Dark inner zone: This part consists of unburnt wax vapour given off by molten wax.It is the coldest part of the flame It is dark because of of decomposed carbon particles. 3) Luminous zone: In this zone partial combustion takes place with liberation of a lot of heat. This zone is hotter than the dark inner zone. 4) Non luminous zone:It is a zone were complete combustion takes placeIt is hottest part of the flame and is hardly visible.

I went to Auto Zone......they ran me off a copy of the belt diagram.....any place like that....Pep Boys, Auto Zone....they will run you off a copy of the diagram
the inner most zone of a flame is less hot because it has unburnt carbon particals and combustion does not take place .thats why innermost zone of flame is less hot
