Chapter 7, Problem 17QP

Interpretation Introduction

Interpretation:

The energy of the photon with a given wavelength is to be calculated and the type of radiation is to be determined,

Concept Introduction:

The energy of a photon can be expressed as follows:

$\begin{array}{c}\text{E}=\text{h}\nu \\ \text{or, E}=\frac{\text{hc}}{\lambda }\end{array}$

Here, E is the energy of the photon, $\text{h}$ is the Planck’s constant $\left(6.63\times {10}^{-34}\text{ J}\cdot \text{s}\right)$ , $\text{c}$ is the speed of light $\left(3.0\times {10}^8\text{ m/s}\right)$ , $\lambda$ is the wavelength and $\nu$ is the frequency.
