Detailed Solution

Incident photon involved in the photoelectric effect may completely disappears or comes out with out change in frequency.
Case I : When frequency of light is less than threshold frequency than no ejection of electrons takes place so, photon comes out with same
frequency.
Case II : When frequency of light is more than threshold frequency, then work function energy is consumed into the ejection of electrons and rest energy is consumed into kinetic energy of electron. So, photon completely disappears.

So there will be no change in the frequency of the incident photon.
