Four momentum of a photon squared, trouble with combining wave-particle duality and energy-f...
Since $p^2=E^2-\vec{p}^2=m^2$ and
$E=h\nu=\frac{hc}{\lambda}$ and
$|\vec{p}|=\frac{h}{\lambda}$
we have that
$p^2=\frac{h^2c^2}{\lambda^2}-\frac{h^2}{\lambda ^2}$
If I go to Planck-units ($c=1 … It doesn't feel right because it depends on the units (SI or Planck) I use. …
