Hello, I tried to read Feynman's book: Quantum Mechanics and Path Integrals but it is so difficult. Is it a really important book if you want to learn Quantum Mechanics? If so what should I do in preparation to read it? Thanks

Why does an atom emit discrete frequencies of light? Solving the Schrödinger wave function for the hydrogen atom (that is a single particle representing an electron bound by a spherical potential) we find that it has discrete energy levels. Plotting every possible value of f in E'-E = \hbar f...

My understanding was that: In the classical picture light is made of waves in the EM field and Maxwell gave evidence for this by calculating the speed of light in terms of electric and magnetic permittivity constants. In the quantum picture light is composed of photons, which are quantum...

Thanks very much it was fascinating to read about spectral linewidth, apparently arising from energy/time uncertainty principle. Does anyone know of experiments or theory that back up the idea that the Schrödinger wave function of a photon has frequencies near to the "classical" frequency the...

In the electromagnetic picture, different frequencies of light waves produce different strengths of diffraction/refraction. In the quantum picture, a photon's energy corresponds to its frequency by the Planck constant E = hf. The solution of Schrödinger's equation for a free particle...

Please help me find "Entropy and Temperature of Radiant Heat" by Max Planck I would like to read "Entropy and Temperature of Radiant Heat" by Max Planck in English. Please help me find this if you have any ideas how. Thank you!
