Calculate the wavelength of the gamma ray photon in (d)(ii).

Photon energy
$\begin{aligned} E=0.48 \times 10^{6} \times 1.6 \times 10^{-19}=\ll 7.68 \times 10^{-14} \mathrm{~J} \gg \lambda=<\frac{h c}{E}=\frac{6.63 \times 10^{-34} \times 3 \times 10^{8}}{7.68 \times 10^{-14}}=>2.6 \times 10^{-12} \ll \mathrm{~m} \gg \end{aligned}$
