## De Broglie wavelength (mass, velocity)

` $$ \lambda ~=~ \frac{h}{m \, v} $$ `

` $$ \lambda ~=~ \frac{h}{m \, v} $$ `

Free online course about quantum mechanics (theoretical physics). Here you learn for example what commutators, observables and bra-ket notation are.

` $$ W ~=~ h \, f ~-~ e \, U_{\text G} $$ `

` $$ \class{red}{f_0} ~=~ \frac{W}{h} $$ `

` $$ W_{\text p} ~=~ h \, \frac{c}{\lambda} $$ `

` $$ W_{\text p} ~=~ h \, f $$ `

Here you will learn the basics of quantum physics - that is, the quantization of nature in the world of atoms.

` $$ W ~=~ \frac{ 13.6 \, \mathrm{eV} }{ n^2 } $$ `

` $$ [ L_{\text x}, L_{\text y} ] ~=~ \mathrm{i} \, \hbar \, L_{\text z} $$ `
