The scattering of a photon by an electron is called the Compton effect.
The scattered photon will have less energy (more wavelength) as compare to incident photon (less wavelength).
The energy lost by the photon is taken by an electron as kinetic energy.
There are three essential requirements for the production of X-rays.
(i) A source of the electron
(ii) An arrangement to accelerate the electrons
(iii) A target of a suitable material of high atomic weight and a high melting point on which these high-speed electrons strike.
In X-ray tube, when high speed electrons strikes the target, they penetrate the target. They loses their kinetic energy and comes to rest inside the metal. The electron before finally being stopped makes several collisions with the atoms in the target. At each collision X-rays may get formed.
When the electron loses whole of its energy in a single collision with the atom, an X-ray photon of maximum energy hνmax  is emitted.

If the energy of electron increased then then wavelength of the characteristic x-ray λ is reduced.
