Why Most of the Fire Flames don’t have Shadows?
Basically, when light is obstructed, a shadow is generated. But we can see that when a bright flame is crossed by a weak light source, no shadow is cast at all. Because a flame is always a source of light, it will not cast a shadow by another source of light going through it. Essentially, one light beam can not interact directly with another.
Can a fire have a shadow? The Reason Behind Fires Can Have a Shadow in a Beam of Light
A fire flame can have a shadow because the flames include hot air, soot, and combustion products, you will see fires cast shadows if you illuminate a flame with a stronger beam of light source. In a light beam, the shadow zone is the area where there is lower light than the majority of the beam.
Why fire flames have different colors?
In the frequent form of flames consisting of hydrocarbon, the oxygen supply and the quantity of fuel-oxygen pre-mixing, influence the rate of combustion and the temperature level of the flame. And this is mainly responsible for the generation of distinct colors in a flame.
