Chapter 9, Problem 9.43E

Interpretation Introduction

Interpretation:

The Bohr’s postulate about the hydrogen atom which is a violation of classical physics is to be stated.

Concept introduction:

The Bohr’s model described the absorption and emission of radiation by an atom through line spectra. The energy emitted or absorbed by an electron is given by the formula,

$E=h\nu$

The formula can be written as follows:

$E=h\frac{c}{\lambda }$

Where,

• $h$ is the planks constant.

• $c$ is the velocity of light.

• $\lambda$ is the wave length.
