Problem: A particle is described by a wave function Ψ(x) = Ae–αx2, where A and α are real, positive constants. If the value of a is increased, what effect does this have on (a) the particle's uncertainty in position and (b) the particle's uncertainty in momentum? Explain your answers.

(a)

Consider the wave function:

Ψ(x)=Aeαx2

If the value of α is increased, the width of the wave function decreases.
