Now you and Sergey have to describe the photoelectric effect using a
wave
model. Either use resonance, or come up with some other mechanism.

Please David, give universal generalized physical
definition of a resonance, which one is valid for
linear and nonlinear physical systems simultaneously.

Resonance is the arrival of momentum in a structure or node that has a
similar direction to both the motion of the structure or node, the
acceleration of the structure or node, and is "in-phase" with it. Rough,
but perhaps close enough...

Remember that resonance already has a definition, and a better one than
mine. It defines a mechanism, and a behaviour, that is contrary to your
needs.
