I have a question,according to Planck’s law absorption or emission always happens as an integral multiple of hv(nu),bt in Compton effect an atom absorbs a fraction of energy of incident photon,can you explain?

Mathew Abraham here absorbed and radiated or emitted photons are different. the scattered photons have greater wavelength and less frequency and energy.

 In Compton effect the photon behaves like a particle which loses some energy due to inelastic collision.
