Question
Cobalt-60 is a radioactive isotope used to treat cancers. A gamma ray emitted by this isotope has an energy of 1.33 $\mathrm{MeV}$ (million electron volts; $1 \mathrm{eV}=1.602 \times 10^{-19} \mathrm{J} ) .$ What is the frequency (in $\mathrm{Hz}$ ) and the wavelength (in $\mathrm{m} )$ of this gamma ray?
Step 1
We know that 1 MeV = $10^6$ eV and 1 eV = $1.602 \times 10^{-19}$ J. So, the energy in joules is given by: \[E = 1.33 \times 10^6 \times 1.602 \times 10^{-19} = 2.13 \times 10^{-13} \, \text{J}\] Show more…
