The uncertanity in two components of angular momentum in quantum mechanics is propotional to the third component. What is the physical picture of this result.
I think u want to ask that the product of uncertanity in two components of angular momentum is greater then or equals to the average value of the third component. As long as I know. it has got something to do with the commutation relation of two components of agular momentum. I can't imagin any physical picture of this result , but it will be interesting if anyone have.
I would like to know how to calculate the ##[\hat{H}, \hat{P}]## for a particle in a 1D box? At the first glance it seems that they commute but they don't get diagonalized in identical basis. How to calculate this commutation?
I don't know why the electrons in atoms are considered in the orbitals while they could be in sates which are superpositions of these orbitals? If electrons are in the superposition of these orbitals their energy expectation value is also constant, and the atom seems to be stable!
