God of Science

When he started to look from the bottom of the burning piece of wood and after his eyes reached the middle portion of the wood which was half burnt, he noticed that at that particular location, the color of this half burnt wood was deep red and as his eyes started to move upwards, he noticed that as the portion of the wood gets more burnt, the color that it releases becomes orange and then at the top from where the fire is spreading out, and gets separated from the surface of the wooden block right into the air, the color of the fire finally turns into complete yellow.

He tried looking once again and starting from the bottom, as the temperature of the wood rises and it burns more and more, the color of the fire produced by that piece of wood also starts to change from red to orange and then finally yellow.

Upon noticing this simple phenomenon of burning that was happening right in front of his eyes, June started digging up the reason for this happening.

It is already very clearly known that there is no particularly fixed color that belongs to the fire.

It can have any possibly imaginable color to it and the color of the fire depends completely only upon the thing or the object that is burning.

For example, during the time of the festivals when the burning of fireworks takes place, you can see all those different varieties of beautiful colors covering the sky.

It becomes very obvious that, many different materials are used to make that combustible mixture which is filled within those multicolored fireworks in order to produce those many different colors. When the firework reaches the sky, that exact mixture burns and then produces a light that is comprised of many different colors.

There are many chemicals also known as 'Pyrotechnic Colorant', which are used in order to produce different colors of fires when they are burnt.

After considering this much, the answer to the question that 'Where does this light comes from?' is finally answered.

Light basically comes in the form of colors, but it only produced from mainly two types of things.

First ones are those things who create their own light by burning themselves like sun and the candle or even the light bulb.

And the second ones are those things who reflect the light that comes from of the first type of things. For like the moon or a mirror.
