1. The problem statement, all variables and given/known data 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? 2. Relevant equations 3. 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.
