Question

Consider X rays of wavelengths 0.2 nm and 0.6 nm. If these suffer Compton collisions with electrons and emerge at the same scattering angle, which have the larger wavelength shift? Which have the larger percentage change of wavelength?

Answer 1

The answe is:

X Ray of wavelength 0.2 nm and X ray of wavelength 0.6 nm have same wavelength shift.

However, the percentage change of X ray of wavelength 0.2 nm is more than that of X ray of wavelength 0.6 nm.

The explanation is elaborated in the following pictures:
