Hi, I've been trying to figure these two questions out but they haven't beeen working. 1. A hydrogen atom is in its fifth excited state. The atom emits a 1090 nm wavelength photon. Determine the maximum possible orbital angular momentum of the electron after emission. Express your answer as...

Could anyone please recommend some beginner-intermediate books on quantum physics for me? I don't want a lot of math, but I would like to learn the basic equations of different phenomena. Thanks.

I've been hearing a lot about "loop gravity" latey. I am not even sure if I am under the right title "quantum physics". In short can anyone tell me what loop gravity is? Thanks

Does free will exist? according to Newton the universe is deterministic, and therefore free will does not fit into this. But since the advent of quantum physics, the universe is not said to be entirely deterministic, is there now room for free will? some physicists believe that the wave...

I have a few questions about quantum physics. First, what is the difference between quantum physics, quantum theory, quantum mechanics, etc? Secondly, I have absolutely no clue about quantum physics. I talked with a friend of mine about it and it seems like something that I would like to...

Hey guys, I'm very interested in physics but I am studying computer science at univeristy so I don't get to learn it formally anymore. However, I still read to learn. I recently read Einsteins book on relativity and Stephen Hawking's A Brief History of Time. I now want to read a good book...

Hello, I am in first year physics and I was wondering if anyone could help me out with a question. Its dealing with Heisenberg's Uncertainty prinicple: A meson is an unstable particle produced in high-energy paritcle collisions. Its rest energy is about 135 MeV and it exisits for an average...

Fill me in -- New to this Hi guys, I've just finished Grade 12 Physics, well almost, but regardless they cut us off at the most interesting part. Our class was just getting into Nuclear Reactors, Half Lives, and the seemingly infinite sub-atomic...energies I guess...(as well as anti-matter and...

Hi, my name is Jeremiah Hendricks and I recently completed a research paper on the effects quantum physics has had in other fields. Part of our assignment is to get feedback on our paper from an appropriate audience. It would be helpful if you guys could read my paper and then answer the quick...

Hello all. I'm new to the forum, and I'm not a physicist. I'm a psychologist. I need some help understanding the meaning of the mathematics applied in quantum physics, when calculating the probability for a particle being located at a certain point in space and time. I understand that there...

I am a first year university student (and have taken chemistry and physics through high school, and still do) and was wondering if anyone had suggestions for reading that would give me a good introduction to the basic background ideas behind quantum physics. I've already learned a good deal...

Can Anyone tell me a good book on Quantum Physics? -benzun

will someone explain to me what quantum physics i watched a show on it but was not compleatly paying attention

For the ground state of the hydrogen atom, evaluate the probabilty density psi^2(r) and the radial probability density of P(r) for the positions. a) r = 0 b) r = rb I confused how this probability function is used. What's the technique here? Thanks

Calculate the smallest allowed energy of an electron were trapped inside an atomic nucleus of diameter 1.4x10^-14 meters. Compare this number with the several MeV of energy binding protons and neutrons inside the nucleus. On this basis, should we expect to find electrons within the nucleus...
