Homework Statement
Show that the de Broglie wavelength of a particle of mass m and kinetic energy KE is given by
[tex]\lambda = \frac{hc}{\sqrt{KE(KE + 2mc^2)}}[/tex]
Homework Equations
The Attempt at a Solution
I know:
[tex]KE = {\gamma}mc^2 - mc^2 = pc - mc^2[/tex]
But from here I am lost. I have a hunch that I need to use the equation that equates Energy and Momentum, but I'm lost.
