Coherent scattering refers to

Also called: Classical scattering or Thompson scattering

●Occurs with energies below 10 keV( involves low energy X-rays)

●Incident x-ray interacts with an atom of matter, causing it to become excited. Immediately the atom releases this excess energy and the scattered x-ray with a wavelength equal to that of the incident X-ray it just changes direction.
