Use Equation (5.25) with Ã(k) = A₀ for the range of k = k₀ - Δk/2 to k₀ + Δk/2, and Ã(k) = 0 elsewhere, to determine ψ(x, 0), that is, at t = 0. Sketch the envelope term, the oscillating term, and |ψ(x, 0)|². Approximately what is the width Δx over the full-widthhalf- maximum part of |ψ(x, 0)|2? What is the value of Δk Δx?
