Chapter 11, Problem 11.47E

Interpretation Introduction

Interpretation:

The reason as to why the given expression for $\text{2-D}$ rotational motion is incorrect is to be stated.

Concept introduction:

The wave function for $\text{2-D}$ rotational motion is given below.

${\Psi }_m=\frac{1}{\sqrt{2\pi }}{e}^{im\varphi }$

Where, ${\Psi }_m$ represents the wave function dependent on quantum number $m$. The values of $m$ start from $0$. Also, it can take up both negative and positive values integral values.
