Chapter 5, Problem 5.ACP

Interpretation Introduction

Interpretation:

In a hydrogen atom, an electron undergoing a change from the second energy level to the first energy level so a photon is emitted in this process, the apparent mass of the emitted photon has to be calculated according to de Broglie relation.

Concept Introduction:

De Broglie relation:

The relationship between energy of a photon, Plank’s constant and frequency is given by,

  $\begin{array}{l}\text{E}\text{=}\text{h}\text{ν}\\ \text{here,}\\ \text{E}\text{-}\text{energy}\\ \text{h}\text{-}\text{Plank's}\text{constant}\text{and}\text{ν}\text{-}\text{frequency}\text{.}\end{array}$
