X-rays with a wavelength of 0..

X-rays with a wavelength of 0.42 nm are scattered from a block of carbon. If the scattered radiation is detected at 71◦ to the incident beam, a) find the wave length of this scattered X-ray. Answer in units of nm. b) Find the kinetic energy imparted to the re-coiling electron. Answer in units of eV. The mass of an electron is 9.10939 × 10^−31 kg, the speed of light is 2.99792 × 10^8 m/s, and Planck’s constant is 6.62607 × 10^−34 J · s.
