In lecture, my professor had drawn the wavefunction for a particle which encounters a potential energy barrier, whose energy it fails to exceed. The graph was highly similar to the...

2 answerIn quantum mechanics, the kinetic energy of a particle described by the wave function $psi$, is related to the curvature of the $psi$. This is easily seen, but...

0 answerFor example I'm thinking about a radial symmetric field like a point charge. The voltage $U$ can be determined by $$int_{r_1}^{r_2} E(r)mathrm{ds} = frac{Q}{4,pivarepsilon_0},left(frac{1}{r_2}-frac{1}{r_1}right)$$ My questions are: why...

2 answerIf the proton were a point charge like the muon, then $epto ep$ scattering, the differential scattering crossection is $$frac{dsigma}{dOmega}Bigg|_{rm lab}=Bigg(frac{alpha^2}{4E^2sin^4(theta/2)}Bigg)Bigg{1+frac{2E}{m_p}sin^2thetaBigg}^{-1}Bigg[cos^2(theta/2)-frac{q^2}{2m^2_p}sin^2(theta/2)Bigg]$$ where $theta$ is angle scattering, ...

1 answerBragg's Law provides a description for the diffraction peaks we observe when x-rays are incident on a crystal structure. We observe these diffraction peaks because the wavelength of the incident...

1 answerIf my understanding is correct, black body radiation is emitted by a substance due to the substances coupling with the electric field. The negatively charged electrons in atoms for example...
