The candle has 4 zones: Blue zone Dark inner zone luminous zone non-luminous zone
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 region where no light penetrates in an aquatic environment is known as the midnight zone. The mesopelagic zone is an area where small amounts of light penetrate.
The zone of a lake where no light reaches is called the benthic zone or hypolimnion, depending on the context. In this area, typically found at greater depths, there is a complete absence of sunlight, which limits photosynthesis. As a result, the ecosystem is primarily supported by decomposers and organisms that can thrive in dark, cold environments. The lack of light also affects the types of organisms that can live there, leading to unique adaptations among the species that inhabit this 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.
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 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 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 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.
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

The non-luminous zone, also known as the zone of complete combustion, is the region within a flame where all fuel is burned completely. In this zone, there is insufficient fuel to produce visible light, resulting in a blue, faintly glowing region. This zone typically occurs at the top part of a flame where oxygen concentration is highest.
