It is better (read this as less distracting) to say it is an energy
phenomenon. At some temperature, a surface will self activate (by
absorption of its own radiated heat), and "free" electrons will be
liberated. Release of electrons from orbitals might be more "frequency
related". The photoelectric effect involves conduction electrons, for the
most part.
Frequency is not so much a property of the photon, as it is a relationship
between the emitter and the receiver. A bolo has a frequency as it
propagates also... as a poor analogy.

Nor should one assume that *any* light is anything other than "both a wave
and a particle". It seems like the best description of any quantum
particle has it born and die as a particle, but live as a wave. The
endpoints are discrete, but the stuff in the middle is woven into the
fabric of the Universe...
