Why can an electron move faster than light within some mediums such as water? What's causing the speed of light to be slowed here but not interacting with electrons?
Because electrons don't get absorbed or reemitted so they have a larger degree of freedom when it comes to movement through a medium?
>>17000375Are photons reabsorbed and reemitted by water?
>>17000385All light is depending on the wavelength and the medium which absorbs certain wavelengths, for example longer wavelengths would probably pass through the water easily, mostly undisturbed.
So what causes the distinctive blue glow of Cherenkov radiation? I know it's the electrons reaching my eye faster than the photons but like why is it blue?
>>17000393From what I'm reading the moving electron basically causes the water molecules around it to polarize in a certain way, but water is already a polarized molecule, so when it snaps back it emits light, but the combined geometry of the medium, motion of the electron/atoms and delay in the normalization of the polarization cause an effective grouping of the light such that the combined wavelength is smaller than what it would normally be, thus appearing blue.
>>17000399Thank you also nice dubs
What is the intensity of the crenkove light inside and operating pressure water reactor? The intense flash from a brief pulse shown in an open pool at a university is quite intense. Does the flux of photons in one particular wavelength result in any physical changes to the equipment?
>>17000399ok how make different colored Cherenkov radiation? what medium to use to make yellow?>inb4: piss
>>17002751I think it's always blue? Cause the medium is your eyeballs
>>17002797But why is it blue? Why not green or red? In every liquid it would be specifically blue? What is thsi arbitrary HORSESHIT?
>>17002834It's not blue in every liquid it's blue in the cytoplasm of your eye. You can only see it as blue because your only optical receptors receive it that way you ape
>>17002836lmao the cameras even record it as blue. what are you on about?
>>17002852Cameras are goyslop anon
>>17002834To give you a real answer anon from what I understand it's because blue is a short wavelength of light and high energy. When it travels through water it's very high energy and thus appears as blue
>>17002855I know what blue is ffs but WHY IS IT BECOMING BLUE?>>17002836>cytoplasm>in animalslmaoing at retard
>>17002834[eqn] \frac{\partial^{2} E}{\partial x \partial \lambda} = \pi c^{2} e^{2} \mu_0 \frac{1}{\lambda^{3}} \left(1 - \frac{1}{\beta^{2} n^{2} \left(\lambda\right)}\right) [/eqn]The emission spectrum is actually continuous, but emitted light decreases pretty rapidly at long wavelengths. The only medium dependent part is in the index of refraction term, and there really isn't really any material where it would vary rapidly enough to compensate for the [math] \lambda^{-3} [/math] term.
>>17002930>The emission spectrum is actually continuousWtf emits continuously?is x the distance the wave travels?
