Question

The three-dimensional wavefunction of a particle is si

Answer 1

Explanation:

The physical interpretation of the wavefunction is that |ψ(r⃗ )|2dV gives the probability of finding the electron in a region of volume dV around the position r⃗ . Probability is a dimensionless quantity. Hence |ψ(r⃗ )|2 must have dimension of inverse volume and ψ has dimension L−3/2.
