We need photons of wavelength 0.0177 nm
When photons interact with matter, there are four competing processes. Compton scattering is one of them.
A photon can be completely absorbed, and its energy can eject an electron from its host atom at energies of a few eV to a few keV, which correspond to visible light through soft X-rays. This phenomenon is known as the photoelectric effect.
The Compton effect was discovered by Arthur Compton.
The Compton effect is the lengthening of electron-scattered X-ray and other electromagnetic wave wavelengths. It is the fundamental process by which matter absorbs radiating energy.
