Homework Statement
In the Compton scattering, a photon of wavelength λ collides with an electron at rest, and a new photon of wavelength λ' emerges at an angle θ. Find λ' y θ.
Energy of incident photon Ei = 1 MeV
Energy of scattered electron Ee = 0.32 MeV
Homework Equations
E = [itex]\frac{hc}{λ}[/itex]
λ' - λ = λc(1 - cosθ)
(λc being Compton wavelength)
The Attempt at a Solution
λ' = [itex]\frac{hc}{E_i - E_e}[/itex] = [itex]\frac{1240 eV · nm}{0.68 MeV}[/itex] = 1.82 pm
θ = cos-1[itex]\left(\frac{λ - λ'}{λ_c} + 1\right)[/itex] = 40.45°
Am I right?
