Chapter 20, Problem 20.13P

Interpretation Introduction

Interpretation:

The path length of the cell has to be calculated.

Concept introduction:

The cell path length can be shown to be given by

$\begin{array}{l}b=\frac{\text{N}}{\text{2n}}\text{.}\frac{\text{1}}{\widetilde{{\text{υ}}_{\text{1}}}\text{-}\widetilde{{\text{υ}}_{\text{2}}}}\\ \text{N}\text{is}\text{maxima}\text{occur}\text{between}\text{wavelength}{\text{λ}}_{\text{1}}\text{and}{\text{λ}}_{\text{2}}\end{array}$
