De broglie phase velocity

WebAug 14, 2024 · The phase velocity of a wave is given by your expression v p h a s e = λ T. This can also be written using different wave variables, that are more commonly used in dispersion relations: v p h a s e = ω k, where ω = 2 π T is the angular frequency and k = 2 π λ is the wavenumber. The group velocity of the wave is defined: v g r o u p = ∂ ω ∂ k. http://www.davis-inc.com/physics/wavegrph.html
