In Compton scattering from stationary electrons the largest change in wavelength occurs when the proton is scattered through _____?
Answer: 180°
Explanation
The change in wavelength (Δλ) is given by the formula: Δλ = h/m0c (1 - cosθ), where θ is the scattering angle.
The maximum change in wavelength occurs when cosθ is -1, which happens when θ = 180°.
