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). Tīmeklis2024. gada 28. dec. · Next replacing f with v/λ (from the wave speed equation, where λ [lambda] is wavelength), and simplifying: \lambda = \frac {h} {mv} λ = mvh. Finally, because momentum p is equal to mass m times velocity v: . \lambda = \frac {h} {p} λ = ph. This is known as the de Broglie equation.

Tīmeklis2024. gada 24. okt. · This is simply given by the energy of the photon divided by c 2: m = E c 2 = h f c 2 = h c λ c 2 = h λ c or λ = h m c. So if you now insert this into the result of De-Broglie: p = h λ = m ⋅ c. So in fact since the velocity of the photon is v = c, you can write p = m ⋅ v. PS: The relation p = m ⋅ v holds for all particles in general. Tīmeklis2024. gada 30. janv. · mv2 = hν.

Tīmeklis2024. gada 12. sept. · De Broglie’s relations are usually expressed in terms of the wave vector →k, k = 2π / λ, and the wave frequency ω = 2πf, as we usually do for waves: E = ℏω →p = ℏ→k. 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.
