I find this easiest to convey with diagrams of the overlapping waves -- you can see when they align and when they cross.

Hear that when tuning a guitar by harmonics until the waves blend.

The technique is sometimes used to achieve ultra high frequencies from relatively low frequency generators.

This is cool you always see people hit one and then show the same one r resonating with the original one across the room without hitting it so it’s cool to see the different waves interfering in different ways

Crazy, I’ve been using beat frequency for almost 30 years when tuning my guitar. I always called them the wiggles. Wiggles go away you’re in tune lol. Thanks for teaching me the proper terminology for said wiggles.
