### Resonance

I'm not sure if I heard this correctly, but I believe it was briefly mentioned that the De Broglie wave equation applies for any particle that has resonance with momentum. What exactly does it mean to have resonance?

I don't if this is what you're talking about, but I know the equation can be used for any particle that has "rest mass", meaning, mass when it is at rest, or inertia.

### Re: Resonance

I'm not exactly sure what resonance of momentum is. However, (fun fact) there is this process called surface plasmon resonance for metal. Basically, when light hits a metal, like gold, the atoms' electron clouds absorb the light and begin moving around. Then, these electron clouds reflect leftover light that was not absorbed. This is actually used in nanoparticle research because surface plasmon resonance explains how nanoparticles can have different colors (they will reflect different wavelengths of visible light).
