comment why does the optical media have different refractive indices?
@Floris I believe Pertunia is using the definition found here: physicsclassroom.com/class/refrn/Lesson-1/…

I tried to edit your question for brevity. Is it still faithful to your question?

@harogaston I agree. It isn't a complete duplicate, so I thought I'd leave it up to the OP.

comment The fundamental equations of electromagnetism
@RyanL Would it always be possible to do so, however? For example, in a system with charges moving with different velocities, there would be no single frame for which all charges are stationary.

In addition, Coulomb's Law doesn't apply for moving charges.

comment Figuring out the time period of an Atwood system
This seems like quite a complex problem to solve analytically without Lagrangian mechanics, unless I'm missing some technique; I'd encourage you to take a numerical approach. You state that this is a simplified version of another problem - what was that problem? It may be easier to solve.

comment Figuring out the time period of an Atwood system
First, your second equation isn't correct if the string is moving along the pulley wheel, since mass $m_2$'s motion wouldn't be circular. Second, you'll probably need to solve a differential equation to determine the total motion -- are you familiar with differential equations?
