Chapter 15, Problem 15.5E

Interpretation Introduction

Interpretation:

The expected positions of the four visible lines of Balmer series for deuterium atoms are to be calculated.

Concept introduction:

Rydberg equation is used to represent the wavenumber or wavelength of the lines present in the atomic spectrum of an element. The Rydberg equation for the hydrogen atom is represented as shown below.

$\overline{\nu }=R\left(\frac{1}{n_{\text{f}}^2}-\frac{1}{n_{\text{i}}^2}\right)$

Where,

• $R$ represents Rydberg constant.

• $n_{\text{i}}$ represents the initial energy level.

• $n_{\text{f}}$ represents the final energy level.
