Homework Statement
What is the minimal amount of energy that a photon needs to create a muon pair?
What is the wavelength of an electron with the same total energy?
Tip: Muons have a rest mass of 1.9*10^-28kg and electrons 9.1*10^-31.
The Attempt at a Solution
I tried to use this formula:
##E_{\gamma} = 2m_{\mu} c^2 + 2\frac{m^2_{\mu}}{m_{nucleus}}c^2##
but there is no atom given I cannot use m_nucleus.
