Chapter 7, Problem 7C.2E

Interpretation Introduction

Interpretation:

For a hydrogen atom present in $1D$ square well of given width, the energy released for a fall from second to first level has to be calculated.

Concept Introduction:

The energy equation for $1D$ is as follows,

$E_n=\frac{n^2{h}^2}{8m{L}^2}\boxed{\begin{array}{l}here,h=Planck\text{'}s\text{constant}\\ m=mass\\ L=\text{length}\\ n=1,2,3,\mathrm{..}\end{array}}$
