Chapter 4, Problem 4.22P

Interpretation Introduction

Interpretation:

Energy of one Einstein of photons of X-rays has to be calculated that has a wavelength of $\text{210}\text{pm}$.

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 ($2.9979\times {10}^8\text{m}\cdot {\text{s}}^{-1}$)
