Chapter 4, Problem 4.23P

Interpretation Introduction

Interpretation:

Energy of one photon has to be calculated if wavelength of radiation is $10.6\mu \text{m}$ and also the number of photons produced per pulse has to be calculated.

Concept Introduction:

Electromagnetic radiations are considered to be a beam of photons.  Energy of photons is expressed in terms of wavelength by the equation given below.

    $E=\frac{hc}{\lambda }$

Where,

    $E$ is the energy.

    $h$ is the Planck’s constant.

    $\lambda$ is the wavelength.

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