1. A photon of wavelength 1.000nm is scattered by a muon initially at rest. What is the deflection angle of the photon if its wavelength after scattering is 1.001nm?
[tex]\lambda[/tex][tex]^{'}[/tex] - [tex]\lambda[/tex] = [tex]\frac{h}{mc}[/tex] (1 - cos([tex]\vartheta[/tex])
Assume that the mass of the muon is 200 times that of an electron.
I have got down to cos([tex]\vartheta[/tex]) = -81.4. I'm not sure what to do now.
