X-Rays with a Wavelength of 0

question 24

Short Answer

X-rays with a wavelength of 0.00100 nm are scattered by free electrons at 130° from their original direction.What is the kinetic energy (in keV)of each recoil electron? (m_electron = 9.11 × 10^-31 kg,c = 3.00 × 10⁸ m/s,1 eV = 1.60 × 10^-19 J,h = 6.626 × 10^-34 J ∙ s)
