WebAt our QM intro our professor said that we derive uncertainty principle using the integral of plane waves ψ = ψ 0 ( k) e i ( k x − ω t) over wave numbers k. We do it at t = 0 hence ψ = ψ 0 ( k) e i k x ψ = ∫ − ∞ + ∞ ψ 0 ( k) ⋅ e i k x d k where ψ 0 ( k) is a k -dependent normalisation factor (please correct me if I am wrong). Webω 0 = ω 2 + ω 1 2; Δ ω = ω 2 − ω 1 2; k 0 = k 2 + k 1 2; Δ k = k 2 − k 1 2 The expression before will be simplified: ψ ( x, t) = 2 A c o s ( Δ k ⋅ x + Δ ω ⋅ t) c o s ( k 0 x − ω 0 t) You will know the phase velocity when you compute v p = ω 0 / k 0 and you will get the group velocity when you compute v g = Δ ω / Δ k. WebNov 19, 2007 · since gravity can be approximated, in a flat Earth approximation, to only act in the up and down direction, the only work done can be in that same direction, i.e. Most of the time you define your first height to have a zero potential energy, so that you just have . how to paste a gif
