Redpill me on light.
What I know:
>a photon that travels like a wave, where the wavelength determines whether it penetrates different matter.
> e=mcc demonstrates the relationship between energy and light
> light is given off during exothermic reactions
> light is given off in LEDs when electrons gain velocity (higher shell) and then collapse into a more stable orbit
So redpill me on light. Give me all you've got.
Also, why does light travel in sine waves? Is the speed of light average displacement or the tangent vector? What can I read/what lectures can I look at to learn more about light?
What is the relationship between light and magnetic fields?

You don't deserve shit.
Light is a subatomic particle. Subatomic particles are only "particles" when their wave form actually touches something. If they move uninterrupted, then they are waves, moving at a constant speed, until refracted or observed.
It is unknown how observation removes a particles' ability to move as a wave at this time.

Yeah, that's pretty clear
Ignoring the SJWtard shitters
Check this out : https://www.youtube.com/watch?v=fnUBaBdl0Aw
It explains the particle/wave behaviour of photons. Also check out double slit experiment which also goes over the similar things.

don't have any links, but check MIT open courseware, they have an introductory E&M class that has a pretty accessible derivation of these equations, of course taking the whole class is best.
The main implication is that in differential form Maxwell's equations in a vaccuum take the formof the wave equation, and predict EM waves, of which light is an example

So then how was I wrong faggot

Light waves aren't displacement waves like on a rope, the sine wave graph you see represents electric or magnetic fields. I.e. when it's positive, the field points one way and the other way when negative, always perpendicular to the direction of travel.

Introduction to Electrodynamics by Griffith
>why does light travel in sine waves?
Not necessarily. It can also be a superposition of sinusoids.
>relationship between light and magnetic fields?
Light is an Electromagnetic Wave (at least in classical Electromagnetism - which can be completely derived from Maxwell's Equations)
In Quantum Mechanics, like everything else, light is both particle and wave-like (as seen in the Dual Slit experiments, photoelectric effect, etc). I don't know a lot about the quantum theory though so if you really want to understand light you also need to read some books on quantum physics.

Thanks anons for references to start looking.
I hope this sheds some "light" on things.
