A particle is described by the wave function φ(x) = 0 for x < 0, φ(x) = Ce^(-x/L) for x ≥ 0, where L = 0.50 nm. (a) Find the constant C using the fact that the particle must be found somewhere on the x-axis with probability 1. In other words, normalize the wave function! (b) Draw graphs of φ(x) and the probability density |φ(x)|^2. (c) Calculate the probability of finding the particle in a region x ≥ 1.0 nm.
