Chapter 7, Problem 7.71P

Interpretation Introduction

Interpretation:

The missing information about the properties of the common type of lasers in the given table is to be determined.

Concept introduction:

The expression to calculate the energy of the photon is as follows:

  $E=\frac{hc}{\lambda }$        (1)

Here, $E$ is the energy of the photon.

$h$ is the Plank’s constant.

$c$ is the speed of the light.

$\lambda$ is the wavelength of the photon.

The relation between the wavelength and the speed of light is as follows:

  $\lambda =\frac{c}{v}$        (2)

Here, $\lambda$ is the wavelength, $c$ is the speed of the light and $v$ is the frequency.
