Chapter 6, Problem 6.12QAP

Interpretation Introduction

Interpretation:

The reflection loss when a radiation ray passes through an empty quartz cell should be calculated.

Concept introduction:

When a beam of radiation passes through two medias with different refractive indexes, a fraction of the beam reflected at interface. The refraction loss is expressed as follows,

$\begin{array}{l}\frac{l_r}{l_0}=\frac{{(n_2-n_1)}^2}{{(n_2+n_1)}^2}\\ \text{Where,}\\ l_0=\text{intensity of the incident beam}\\ l_r=\text{reflected intensity}\\ n_2,n_1=\text{refractive indexes of the two media}\end{array}$
