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? Homework Equations The Attempt at a Solution so I used...

Why are the atmosphere's main elements ( Nitrogen and Oxygen) transparent to visible light. And what makes most gases have low absorption?

Why can visible light pass among glass? Why glass is is transparent to visible light?

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. TIA, yert

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 ?

why are some things transparent like glass and others opaque like some metals or plastics? thank you

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...

Does a transparent material exist which can shield against galactic cosmic rays i.e. high energy nuclei of light elements?

Why some things are transparent while others not?:confused:

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...

can anyone tell that why is snow white while water transparent?

I have never really thought about so any help would be great.

Does anyone know why glass is transparent?
