why we find expectation value? why do we take expectation value of sime entity? and how come we know that our expected value is correct

in polystyrene bead placed in lase, only the refracted wave is responsible for electrical gradient not the reflected one. how come it is so

how come there is an electrical gradient in lasers? i means lasers are just monochromatic photons so how come a particle feels an electrical force there

if we want to find the probability of a wave function let ψ we use <ψ|ψ> when there is no change in wave function. but when we previously have wave function ψ and we quadruple it then wavefunction becomes ψ' the probability is found by |< ψ'|ψ>|^2. why we take square in this case? i can't...

but my teacher has asked for significance and applications, and from your point there won't be any of them. moreover my teacher has told us that lorenz gauge can give us pure scalar and vector potentials. but coloumb gauge can not. is it true? and what is the logic behind it

i am searching the physical significance of lorenz and coloumb gauge but can't find anything besides that coloumb gauge is used for finding time independent potentials while lorenz is for finding time dependent potentials. and i'll be really grateful if u give me applications of then in any field.

thaks a lot mfb

can you give me a little detail of it please

i don't think he would consider it as an application, but can't it be placed in some other portion of my assignment?

can anyone tell me the applications of radiation pressure? i have manged to find out one application i.e in solar sails but still my instructor is demanding more applications. i have also found an abstract of an article its about Adiabatic electron thermal pressure fluctuations in tokamak...

i have been searching for this but can't find a satisfactory answer

but why sw? why we need it at the first place? we do have primitive cells in structures. so why this special case

can anyone tell me the physical significance of weigner seitz cell
