Nov 21 asked branch points of arcsin Nov 19 comment Reflectance and phase shift vs incident angle and wavelengthi thought so too, but the question asked to plot the graph for different wavelengths of the same refractive index N of the substrate :O Nov 19 awarded Editor Nov 19 revised Reflectance and phase shift vs incident angle and wavelengthdeleted 46 characters in body Nov 19 asked Reflectance and phase shift vs incident angle and wavelength Nov 13 accepted Wave function of Hydrogen Atom Nov 13 comment Wave function of Hydrogen AtomTHank you, just a small question: so it s ok to use $\langle\psi_n|E|\psi_n\rangle=-13.6eV/n^2$ ? Nov 13 awarded Supporter Nov 13 comment Wave function of Hydrogen Atomalso, is there any short, elegant way to calculate $\Psi*E\Psi$, $\Psi*L^2\Psi$, $\Psi*L_z\Psi$, Thank you ~ Nov 13 comment Wave function of Hydrogen AtomP(100)=2/7, P(200)=9/14, P(322)=1/14 P(otherstate)=0 i already knew this. How to check if this is an eigen function of parity ( if it's an even or odd function) ? i feel i need to understand each subscript and how they behave under parity operator Nov 13 asked Wave function of Hydrogen Atom Nov 13 awarded Scholar
