What change in wavelength is expected when X-rays are scattered at 90°? A) 3.75 × 10^-3 nm B) 4.84 × 10^-3 nm C) 2.42 × 10^-3 nm D) 1.18 × 10^-3 nm E) no change at this angle

Question

Quizplus · Accepted Answer

The change in wavelength for X-rays scattered at 90° is given by the Compton wavelength shift formula: Δλ = h/(m_ec) * (1 - cos(θ)), where θ = 90°. This results in Δλ = 2.42 × 10^-3 nm.
