Chapter 7, Problem 7D.1E

Interpretation Introduction

Interpretation:

For a particle at $\text{2}\text{D}$ ring of radius $\text{100}\text{pm}$, the wavelengths of wave functions have to be calculated for three lowest rotating levels.

Concept Introduction:

The wave functions that matches after circuit which has the integral number of wavelengths fits around the circumference then, the wave function can be represented as follows,

$\begin{array}{c}\lambda =\frac{2\pi r}{n}\\ n=0,1,2,\mathrm{...}\\ \boxed{\begin{array}{l}here,\\ \lambda =wavelength\\ r=radius\\ n=rotationallevel\end{array}}\end{array}$
