Chapter 14, Problem 69E

Interpretation Introduction

Interpretation: The initial state of the line with the given value of final state and wavelength of radiation in the given spectrum is to be determined.

Concept Introduction: The initial state of the line in the given spectrum is calculated by using the formula,

$\frac{\text{hc}}{\text{λ}}=\left(-2.18\times {10}^{-18}\text{J}\right)\left(\frac{\text{1}}{{\text{n}}_{\text{f}}^{\text{2}}}\text{-}\frac{\text{1}}{{\text{n}}_{\text{i}}^{\text{2}}}\right)$
