Chapter 7, Problem 7.9QAP

Interpretation Introduction

(a)

Interpretation:

The thickness of dielectric layer needs to be determined when the interference filter is of first-order.

Concept introduction:

Calculation of the thickness of the dielectric medium is done by the following formula-

$\lambda =\frac{2dn}{n}$

And the relationship between wavelength and wave number will also be used:

$\lambda =\frac{1}{\overline{v}}$

Interpretation Introduction

(b)

Interpretation:

Wavelengths transmitted from interference filter at different orders needs to be determined.

Concept introduction:

Following formula will be used for the calculation of wavelength at different order of interference filter-

$\lambda =\frac{2dn}{n}$
