Chapter 4, Problem 4.16P

Interpretation Introduction

Interpretation:

Frequency of radiation that has a wavelength of $\text{589 nm}$ has to be calculated.

Concept Introduction:

Radio waves, infrared light, X-rays, gamma rays, microwaves and visible light are all the forms of electromagnetic radiation.  In electromagnetic spectrum, wavelength is the distance between two successive crests or trough.  Number of crests passing a given point per second is known as frequency.  Wavelength $(\lambda )$ and frequency $(\nu )$ are inversely related.  Speed at which a wave travels is the product of frequency and wavelength.  This is expressed by an equation given below.

    $c=\lambda \nu$

Where

    $c$ is the speed of light ($2.9979\times {10}^8\text{m}\cdot {\text{s}}^{-1}$)

    $\lambda$ is the wavelength.

    $\nu$ is the frequency.
