Chapter 20, Problem 20.27P

(a)

Interpretation Introduction

Interpretation:

A graph of n versus $\text{λ}$ has to be marked.

Concept introduction:

The graph was drawn using given formula

Wavelength = $\frac{{\text{λ}}_{\text{o}}}{\text{n}}$

$\begin{array}{l}{\text{λ}}_{\text{o}}\text{is}\text{the}\text{wavelength}\text{in}\text{vacuum}\\ \text{n}\text{is}\text{the}\text{refraction}\text{inden}\end{array}$

(b)

Interpretation Introduction

Interpretation:

The graph against wavelength and refractive index has to be plotted.

Concept introduction:

The draw the graph using given formula

Wavelength = $\frac{{\text{λ}}_{\text{o}}}{\text{n}}$

$\begin{array}{l}{\text{λ}}_{\text{o}}\text{is}\text{the}\text{wavelength}\text{in}\text{vacuum}\\ \text{n}\text{is}\text{the}\text{refraction}\text{inden}\end{array}$

$\frac{\text{dn}}{\text{dλ}}$
