WebFeb 5, 2024 · Finding the angle of the scattered electron does involve the Compton relation. First, convert the photon energies into wavelengths: Ephoton = hc λ λ = hc E = 1240 eVnm 800 keV = 1.55 × 10 − 3 nm = 1240 eVnm 650 keV = 1.91 × 10 − 3 nm then use the relationship λ ′ − λ = hc mc2(1 − cosθ) WebUsing the distance formula and the cosine rule, we can derive the following identity for compound angles: cos(α −β) = cosαcosβ + sinαsinβ cos ( α − β) = cos α cos β + sin α sin β.
