Chapter 11, Problem 13E

Interpretation Introduction

Interpretation:

The source of the observed lines in the hydrogen spectrum is to be explained with the help of a sketch of the Bohr model of an atom.

Concept introduction:

According to the Bohr model of the hydrogen atom, the electron is allowed to circle the nucleus only at certain radii with certain energies. An electron in the ground state energy level, $n=1$ can absorb a certain amount of energy to raise it to any other higher energy level, $n=2,3,4$ in one or more steps.
