Maths, calculus, differential equations, linear algebra and eventually operator theory. Physics, study all the basic physics first like Newtonian mechanics, Electromagnetism, special relativity and basic modern physics. Basically what you learn in a physics course at uni, until you get to...

It's correct. The masses are irrelevant.

The Refractive index can be inferred from electromagnetic theory, and density of material. I can tell you that Helium has the record lowest refractive index of all the elements. As for spectral absorption which is more important, that may be calculated with perturbation theory in Quantum...

Well, we know a lot, and then we don't know a lot. Some questions can be answered, some cannot. We can make a lot of very accurate predictions and all. Classically the radio wave and x-ray are oscillations in the magnetic field, and the electric field, which is usually a good enough answer...

Well, unfortunately nobody really knows beyond that, quantum physics doesn't say anything about the underlying nature of reality, or structure of reality. All of that is philosophically left open. All that it does describe, is what we can measure. There are different philosophical...

These properties (light absorption spectra ) can be experimentally verified, measured, however it is too complicated to compute from pure physical theories. The theories pertaining to light absorption and so on are quantum physics, which don't permit easy computation - anything beyond a helium...

From what I've learned, the black hole doesn't lose mass, that which it captures it keeps, i.e. nothing is "passed through".

If b is a constant, then yes that is valid. We can change the variable you are integrating with respect to, with substitution, and it's a nifty trick for integrals. d(x/b) is jus dx/b or (1/b) dx so you can take the constant term out like that.

Wavelength is still wavelength. Different waves have different wavelengths just as you imagine. As for the probability density, that means that the wave is localized (confined to a certain area, sort of like a particle), but it's still a wave. The picture you're looking for is a wave packet...
