Answer:

  • [tex][\psi]= [Length^{-3/2}][/tex]
  • This means that the integral of the square modulus over the space is dimensionless.

Explanation:

We know that the square modulus of the wavefunction integrated over a volume gives us the probability of finding the particle in that volume. So the result of the integral

[tex]\int\limits^{x_f}_{x_0} \int\limits^{yf}_{y_0} \int\limits^{z_f}_{z_0} |\psi|^2 \, dz \,  dy \,  dx[/tex]

must be dimensionless, as represents a probability.

As the differentials has units of length

[tex][dx]=[dy]=[dz]=[Length][/tex]

for the integral to be dimensionless, the units of the square modulus of the wavefunction has to be:

[tex][\psi]^2 = [Length^{-3}][/tex]

taking the square root this gives us :

[tex][\psi] = [Length^{-3/2}][/tex]
