Homework Statement
Photon with ##\lambda =10^{-12} m## hits an electron (Compton scattering). After the interaction the photon and electron move under relative angle of 90°. Calculate the kinetic energy of electron. Hint: First find the relation between ##\theta ## and ##\varphi##. (##\theta +\varphi = 90°##)
Homework Equations
The Attempt at a Solution
I can't find the relation! How on Earth can I find it?
The only thing I get from components of momentum is: ##\frac{hc}{\lambda ^{'}}sin\theta =cp_esin\varphi ##
But this doesn't help me much... or does it?
Please help.
