Chapter 4, Problem 55E

Interpretation Introduction

Interpretation:

The energy level change that is most energetic, among $4\to 1,3\to 1$ and $2\to 1$, is to be stated.

Concept introduction:

The concept of electron energy level was supported by the line spectrum of hydrogen. In a gas discharge tube, excited atoms of hydrogen have electron in a high energy orbit. In the process, when electron drops from the higher energy level to lower energy level, the electron loses a discrete amount of energy.
