WebSep 12, 2024 · 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.
