Sorry for lack of clear expression, basically i meant that a particle is described by its wavefunction, probabilities are linked to a wavefunction. I meant the quantum mechanics as given in griffith's book. We don't consider any types of field in that mechanics. And yeah I don't have any idea of...

So we can confidently say everything exist in form of fields (or whatever quantum field theory is about)! But the quantum particle model of wave function, are both equivalent? One of those two must be correct right.

Well i really really wanted to sum up what i understood, please point if i interpreted it wrong. So basically we don't know what electromagnetic radiation is or what matter is. All we do is make a theory for matter that is described by a wave function,operators and all and we consider it...

Hi, i am doing an introductory course in quantum mechanics (that would be equal to first two chapters in griffith's quantum mechanics). I have the doubt that what exactly do we consider in quantum mechanics. Let me say like the electron is a particle and when we will observe it will have a...

Well i am noobie to quantum physics so i matbe totally incorrect so please bear with me. I had question how is position operator defined mathematically. I was reading the momentum position commutator from...

Before applying angular momentum conservation think about 2 things. First: point about which you are applying angular momentum conservation. Whether point is stationary or moving or accelerated. If accelerated you have to apply pseudo force to CENTER OF MASS OF THE SYSTEM ON WHICH YOU APPLY...

If i add two sine wave functions (real parts) envelopes are formed. So group velocity must not be dw/dk. Asking coz my proff said that which i feel is wrong

How did they put the linearization equation? Was there approximate and then it could really be applied for wavefunction approaching delta functions

Could you please explain the derivation of group velocity = dw/dk I read ut here https://en.m.wikipedia.org/wiki/Group_velocity Is it approximation, if so under what circumstances

I read a line in the book "Quantum physics of atoms, molecules, solids, nuclei, and particles" by resnick The line is "in classical physics energy is either Transported by waves or by particles" I have doubt is it correct, like we say eneegy is stored in electric field, is electric field...

Ok, so can we say probablity at a point is zero always. And is electron point object??

I have started quantum mechanics on my own using online lectures. So i have very basic doubts: 1) probability of electron is defined in space rather than a point. My question is why don't we comment about probability at a point. I thought two possible explanation that: 1.1)ψ2dx the dx term...
