TīmeklisThe plane matter waves of a free particle moving with speed v has the form ψ (x,t) = Acos (kx - ωt + φ). This wave function has a well defined wavelength λ = h/p and a well defined frequency f = E/h. We have p = h/ λ = ħ k and E = hf = ħω. But for a free particle we also have E = mv 2 /2 = p 2 / (2m) = ħ 2k2/ (2m).

Wave theory tells us that a wave carries its energy with the group velocity. For matter waves, this group velocity is the velocity u of the particle. teak rundstavTīmeklis2024. gada 20. nov. · This forces them to be proportional, with an identical proportionality constant α. From the Einstein relation E = h ν it is then natural to guess at α − 1 = h, and indeed this gives the correct De Broglie relations, including the ones you quote. Once we accept this, everything follows directly. As we see, the De Broglie … ek plaza parking
