Hmm, quantum physics?

[Tachyon]

Would be helpful, if you stated in which detail you have to know these things and whether you're familiar with the basics of quantum physics (consult wikipedia?).

Implying you know plenty about classic physics + waves, here's some basic stuff for you.

Search for "quantization of certain physical properties", "wave–particle duality", "principle of uncertainty", "quantum entanglement" in Wikipedia (found all of it there) for an introduction into the four basic principles of QP.

Next you should get familiar with the behaviour of quantum objects and energy (models of electrons in atoms and their energy states, absorption, elastic & inelastic scattering in general, light/photons). -> E=hf
A nice experiment with electrons on this topic is the photoelectric effect (->Einstein) [E=eU0 for photoelectrons]
Electrons in atoms - Franck-Hertz experiment
The amount of energy an atom absorbs is characteristic for that atom => Each atom absorbs a certain energy value


DeBroglie, Energy of a quantum object: E=hf, λ=h/p (h= Planck constant, p=impulse of photon)

Bragg: k*λ=2a*sinϑ (sinϑ = angle at which photon/wave approaches scattering surface, λ = wavelength, a = distance between layers of scattering surface)

Compton effect/scattering:

m*= E/c²= hf/c² (*mass of a photon)

Δλ = (h / m0e * c) * (1-cosφ)
-> Δλ that's the change of the wavelengh when a photon is scattered by an electron (that's the Compton effect/scattering)
-> h is Planck's constant
-> m0e is the rest mass of the electron that scatters the photon
-> c is the speed of light (constant)
-> cosφ is the cosine of the angle the photon approaches the electron with

Hopes this helps, feel free to ask about details about anything of the above.
