Chapter 9, Problem 9.9E

Interpretation Introduction

Interpretation:

The wavenumber of given light in units of ${\text{m}}^{-1}$ and ${\text{cm}}^{-1}$ is to be expressed.

Concept introduction:

Wavelength is a measure of the distance between two adjacent crests or toughs. The wavelength of light is inversely proportional to the energy and frequency of the light. Wavenumber is mathematically equal to the inverse of wavelength. The relation between wavelength and wavenumber is represented as,

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

Where,

• $\lambda$ represents the wavelength of the light.

• $\overline{\nu }$ represents the wavenumber of the light.
