Photoelectric effect compared to the particle theory

[*intheclouds*]

Homework Statement

in the photoelectric effect, if the frequency of the radiation is below a certain cutoff frequency, no photoelectrons are produced no matter how intense the radiation is. Why does this fact favor the particle theory over the wave theory?

Homework Equations

The Attempt at a Solution

I know that the particle theory was that all light was made up of particles. I also know that the photoelectric effect has photoelectrons emitted under correct conditions. What I do not understand is how to use both of those concepts to explain the answer to this queston.

In the particle theory, each photon must have enough energy to overcome the work function of the material containing the electrons.

Do you know how photon energy and frequency are related?
