Simple harmonic potentials & classical waves

[gildomar]

Homework Statement

It's not a direct question, but it's an implied part of a larger question: can classical waves experience simple harmonic oscillator potentials, like a mass on a spring does?

Homework Equations

The Attempt at a Solution

I'm thinking no, since I can't come up with a scenario where classical waves would experience such a potential. The closest that I got the waves interacting with a parabolic dish, but I wouldn't really consider that an oscillator potential.

I can't think of one either.
