In Compton׳s scattering process, the wavelength of scattered X-rays :

Explanation

In Compton's scattering process, the wavelength of scattered X-ray increases. Compton scattering is a type of scattering of electromagnetic radiation by a charged particle, usually an electron. In this process, a photon (x-ray) collides with an electron, and the photon transfers some of its energy and momentum to the electron. As a result, the photon's wavelength increases, and its frequency decreases. The change in wavelength is given by the Compton formula: Δλ = h/mc(1 - cosθ), where Δλ is the change in wavelength, h is Planck's constant, m is the mass of the electron, c is the speed of light, and θ is the angle between the incident photon and the scattered photon.
