Webb4.2 Probability and normalisation In the previous lecture we introduced the idea of probabilities based upon the wave function. The probability P(x)dxof observing a particle between xand x+dxis P(x)dx= Ψ∗(x,t)Ψ(x,t)dx. (16) The probability of observing the particle between x 1 and x 2 is P= Z x 2 x 1 Ψ∗Ψdx. (17) WebbFor example, in our free particle solution, the probability density is uniform over all space, but there is a net flow along the direction of the momentum. We can derive an equation showing conservation of probability by differentiating and using the Schrödinger Equation.

Sorted by: 2. The short answer is because the sine wave is the slowest at the peak. If you imagine a pendulum (which is basically a sine wave ), it's slowest at the extremes, and fastest at the bottom. As a sine wave the pendulum's bottom is the zero, and the extremes are -1 and 1.
