So, i was thinking about this and figured out this: depending on electron orbit and, corespondingly, speed around the nuclei and energy of the photon, if the electron makes full cycle by the time it re-emits that photon the material is reflective - electron is in the same position where it...
hi everyone...
i have got a general doubt...I have heard that silicon is transparent to
infrared...so does that mean that any IR wave entering silicon comes out of it without any change? Is silicon 100% transparent to IR? does the transparency depend on temperature or any other parametre...
I witnessed a rather incredible aerial phenomenon years ago with naked eyes. It was around 2:00AM and a very clear night. As I was talking with someone, I caught something out of the corner of my eye above while I was talking with someone. It was cylindrical-shaped (although the ends seemed...
Hi guys. I have a small problem with viewing Latex symbols here. Formerly the white background of the Latex symbols enabled here would be transparent which makes the Latex display slightly better. However, due to a period of inactivity lasting slightly over 2 weeks it seems to me that either...
Homework Statement
Parallel light rays enter a transparent sphere along a line passing through the center of the sphere. The rays come to a focus on the far surface of the sphere. What is the sphere's index of refraction?

I was having a glass of wine over candlelight and I noticed that the liquid wax was completely transparent but turned opaque when when the wax solidified. Why does this happen? Clearly, when the molecules reorganize during the freezing phase transition they begin to interact with the light. What...
As I understand it, conductors interact with EM waves (light) in such a way that
prevents transmission through the conductive material.
Given this, why aren't all insulators transparent?
Why is SiO2 transparent, but Si by itself is not?
Any and all information helpful.

Hello,
I have a camera I am using to monitor some items, and the shield for it is exposed to a lot of mist (oil-based ink). An issue I am having is that this guard is quickly becoming covered, rendering the camera useless. It is dificult to access the camera, so cleaning it by hand becomes...
Why is glass "QM transparent"?
Sorry if this is a basic question.
Why is a wave state preserved through it's interaction with glass, mirrors, air, etc.? Why doesn't reflection (absorbtion then re-emission) fix the position and collapse the function? It's isn't really the same photon that...
Glass is a solid? It is made up of molecules which is similar to what many other solids are made of? Then why is it transparent? Is it that the color of the molecules in glass are transparent and those in other solids are not? For that matter what is the color of molecules(atoms) in general?
Homework Statement
Suppose a reflected white light is used to observe a thin transparent coating on glass as the coating material is gradually deposited by evaporation in a vacuum, Describe color changes that might occur during the process of building up the thickness of the coating...
hey
what in an atoms struture tells us if the element is going to be transparent or opaque ?
what in an atoms structure tells us at what frequency photons will come out with after hiting the electrons ?
There is a HUGE debate going on over at another forum i frequent, several people are claiming that their turbos become translucent at extreme temperatures. They claim they are able to see the turbine wheel spinning through the housing.
Another group is claiming that what you are seeing is not...
The fact that light has a smaller apparent speed in a transparent medium can be explained classically by considering the motion of the electrons of the medium in the oscillating (radiation) electric field produced by the source. Because they accelerate, these electrons emit an electric field...
