frequency of incident radiation
intensity of incident radiation
both frequency and intensity of incident radiation

I think in photoelectric emission, the energy of the emitted electrons does not depend on the intensity of the incoming light or the intensity of incident light, but only on the energy (equivalently frequency) of the individual photons. It is an interaction between the incident photon and the outermost electrons.

How only intensity could result in photoelectric emission when we have e=h*frequency?
