Chapter 19, Problem 59E
Interpretation Introduction

Interpretation:

The wavelength associated with the photons produced by the annihilation process of a positron and an electron is to be calculated.

Concept introduction: Positron is antimatter partner of an electron. They annihilate with each other and release two photons with total energy equal to the sum of masses of the electron and positron. When an electron and positron annihilate one another, the resulting mass is completely converted to energy.

To determine:The wavelength associated with the photons produced by the annihilation process of a positron and an electron.
