why compton effect cannot observed by visible light?

Visible lights have enough energy to knock out electrons but energy is converted into KE of electrons emitted and initial photons are lost. If the photos are gone they can't scatter. Compton effect happens with visible light but its so less that it is unobservable. Any new photons are used by increasing KE of electrons. It becomes observable when photons energies are in range of 100eV that happens in case of X-rays.

In Compton effect the energy of the photon should greater than binding energy of electron in metals the threshold frequency is equal to that of ultraviolet light the visible light energy is low so Compton effect is not noticed in visible light
