If an X ray of wavelength 1.000 Å and a γ ray of wavelength 0.030 Å undergo Compton scattering at a scattering angle θ, then:
1
For X rays, \( (\Delta \lambda)_{\text{max}} \) is observed at \(\theta = 180^\circ\)
2
For γ rays, λ' ≈ 0.035 Å} at \(\theta = 90^\circ\)
3
For X rays, \(\lambda' \approx 1.098 \, \text{Å} \) at \(\theta = 90^\circ\)
4
For γ rays, \((\Delta \lambda)_{\text{max}} \approx 0.005 \, \text{Å}\)
