A 140-KeV Photon Strikes an Electron and Scatters Through an Angle

question 74

Short Answer

A 140-keV photon strikes an electron and scatters through an angle of 120° from its original direction.(m_electron = 9.11 × 10^-31 kg,c = 3.00 × 10⁸ m/s,h = 6.626 × 10-34 J ∙ s)
(a)What is the wavelength of the photon before scattering?
(b)What is the photon wavelength after scattering?
