Chapter 7, Problem 2SAQ

Interpretation Introduction

Interpretation:

The option corresponding to the electromagnetic radiation that contains greatest energy per photon is to be identified.

Concept Introduction: if an atom absorbs energy then this atom gets excited from the lower energy orbital to the higher energy orbital. The energy absorbed by an atom is calculated by the Planck’s equation. This equation states that energy is inversely proportional to the wavelength as,
   $E=\frac{hc}{\lambda }$

Where,

• $E$ is the energy absorbed by the atom.
• $\lambda$ is the is the wavelength of light.
• $c$ is the speed of light.
• $h$ is the Planck’s constant.

To determine: The option corresponding to the electromagnetic radiation that contains greatest energy per photon.
