Welcome back friends this is simple science and today I am going to describe why glass is transparent. Once this question also confused me. I always think, glass is a solid body like a wall and stone then how light passes through it. If you also get stucked in this question then read this post, I will try to describe it in a very simple way.

Why glass is transparent?


As we know that, everything in this world is composed of atoms which consists of electron, proton and netron. Atoms are the smallest part of any material which possess the properties of that material whether it is the physical or chemical property. Like a block of pure carbon (coal) burns in the presence of oxygen once it get heated to a certain temperature. This property of the block came from the property of its atoms. Each carbon atoms combines with two oxygen atom to form carbon dioxide and this chemical reaction gives heat and light.

Now take a look on the structure of an atom. An atom has a nucleus which is present at its centre. It consists of proton and neutron which is bounded with strong nuclei froce also called strong interaction. Whole mass of an atom is just concentrated at its centre. Inside an atom electrons are just revolving around the nucleus. And the distance between them is very much if we compare it with their sizes. You can better understand it with this example, if the nucleus of an hydrogen atom get the size of a football then its electron will be five kilometer away from its nucleus.

So, we can say that an atom has lots of vacant space. So here is the answer of this question. Glass is transparent because it is made up of atoms and as atoms consist lots of vacant space inside it that's why light passes easily through it and makes glass transparent. But with this answer a new question arises, that is ' If atoms consists lots of vacant space inside it then why not everything is transparent?' 

The answer of this question could be given with quantization of energy. Glass is composed of silicon dioxide which do not absorb any visible light. That's why all visible light can pass through a glass. Property of absorbing and reflecting light makes a material opaque. Different materials have different property of absorbing and reflecting light that's why they have there specific color. I hope you got your answer, if you want to read more about the 'quantization of energy' then, click here.
