What is the primary factor that causes the Compton shift during photon-electron scattering?
Answer and explanation
Correct answer: A. Scattering angle of the photon
- Step 1: The Compton scattering equation is .
- Step 2: The change in wavelength depends exclusively on fundamental physical constants () and the scattering angle .
Answer
Scattering angle of the photon.
Why not the others: 'Intensity of the incident photon beam' affects the rate of photon events, not the wavelength shift; 'Temperature of the target material' does not alter the fundamental scattering equation; 'Mass of the incident photon' is invalid because photons are massless.
