Chapter 20, Problem 20.96QP

Interpretation Introduction

Interpretation:

Wavelength of a gamma emission has to be calculated and the mass difference in Tc-99 and Tc-99m has to be predicted.

Concept introduction:

The formula for calculating wavelength

${\text{E= mc}}^{\text{2}}$

Where,

m- Mass of the particle

c- Velocity of light

Rearrange this equation to find energy,

$\text{E=}\frac{\text{hc}}{\text{λ}}$

Where,

$\begin{array}{l}\text{h - Plank's constant which is equal to 6}{\text{.626×10}}^{\text{-34}}\\ \end{array}$
