What is the Compton shift for the scattered x-rays?

X-rays with a wavelength of 0.10 nm are scattered from an argon atom. The scattered x-rays are detected at an angle of 85 degree relative to the incident beam. What is the Compton shift for the scattered x-rays? a) 0.0022 nm b) 0.011 nm c) 0.022 nm d) 0.041 nm e) 0.12 nm

Solution
