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 are the frequency (in $\mathrm{Hz}$ ) and the wavelength (in $\mathrm{m}$ ) of this gamma ray?

Step 1

The energy of the gamma ray is given as 1.33 MeV. We know that 1 eV = 1.602 x 10^-19 J. Therefore, the energy in Joules is given by: E = 1.33 MeV x 10^6 eV/MeV x 1.602 x 10^-19 J/eV = 2.13 x 10^-13 J Show more…
