How can we possible see through any solid? Unless glass is really liquid. Cause as we all know liquid has it's molecules spread out that is not enought to block the passing light trough it.
Hos can we possibly see trough GLASS?

My best answer would be because it is clear ;) You can make glass dark enough so it is hard to look through...

Well glass is obviosuly not a liquid, but when it is warm it certainly turns into liquid ;)

When the light falls on an object the electrons in the atom of that object will absorb the light and jump to a higher level. The energy difference between these 2 levels of the electron will be equal to the photon energy of the absorbed light. If the energy difference between the present energy level and the highest available energy level is less than the energy of a photon of a particular light then that object cannot absorb that particular light. And it will be transparent for that light. The electrons available in the glass has no energy level high enough to carry the energy of a light in the visible range so it is transparent to visible light. Infrared lights have less photon energy than visible light. So electrons of the glass could absorb the photons of infrared light. So glass will be opaque to infrared light. That is the reason why glass could trap infrared and act as a green house.
