Why is glass transparent | Why light passes through glass

Why we see through glass is because it is transparent and light can pass through it. It cannot pass through a paper and it is opaque. In this episode, the reason for optical transparency is explained from the basics with the help of analogies and animations. The physics behind this is comprehensively explained in simple language with the aim that a common man without any scientific background should also be able to understand.

Thank you so much sir. Keep continuing this work. We will keep supporting you.

[thewayoflearning]

Sir i think,
There is some missing element, because if we apply light continously on paper material, at some time elecron reaches at its maximum energy states, and it have to behave like fluorescent objects, and also this theory not follow energy conservation, so i thinks there's something missing

I'm watching this vid to understand something our doctor said about transparency of cornea of eye. He said that the distance between the arranged fibers is less than wavelength of light. What can that mean in the eye of physics?

[UrmilaDevi-icgh]

Sir what happens to the electrons of the opaque materials when they gain energy from photon do they become charged or what ??

[pragithu]

One doubt, when electrons already excited and further photons comes, wat will happen to them..? Will pass?

[jeeaspirent]

If difference in energy level in opeque object is less then transparent object then why soem transparent object behave as conductor and opeque object are

[rosieroti]

despite that, there is vastly more empty space between the molecules too, which should have allowed majority of the light to pass through to make almost everything transparent. why does it not happen?

[thethinkingman-]

when the frogs catch all the flys they will be on the higher levels.
does this mean the paper is transparent after all the frogs are on the high level?

[arunar]

Informative & Simple explanation.. Thank you sir🥰

[mikefixac]

Thank you for this video it was very informative. My question is this: so are the valances farther apart in glass than in other objects, therefore the electrons don’t absorb the light protons?

[habentesfamariam]

Thank you good sir. me and warsay was wondering about how to be an invisible man!

[twinkleharchandani]

Why energy provided by photons is not enough for a glass to absorb it.
What atoms are their in a glass??

[silenhinkee]

So does this mean if theres a wall and theres a 3 dimensional creature and theres 2 2 dimensional creatures the 3 dimensional creature can see that wall because its 2 dimensional wall🧐

[mohammedqusailah]

We see the ball is ~ Red, because it absorbs all color's lights and recreated the Red one. That's why we see the objects with their colors.
The frequencies which they are not accompany to red color, we say, they were absorbed and the material not able to reemitted them again, which they may will be used to gain the molecules a kinetic energy then to increase their temperature.

But you have completely reversed the concepts in your explanation.
The frogs will go back to their places and then the flies must be spited. Finally, when reach the surface we will see the flies. But the truth is "we will not see them".

THen y x rays & gamma rays pass through opaque material. They should engage with electon and stay there too

[Theninjagecko]

A photon isn't that small. There's something else going on.
