Cubic harmonic

Imagine you have a toy block that is shaped like a cube. Now, imagine that you can make the cube vibrate like a bell when you hit it. The sound it makes is called a cubic harmonic.

A cubic harmonic is like a musical note that you can play on a cube-shaped object. It has a specific frequency and wavelength, which determine how high or low the note is and how long it takes for the sound waves to complete one cycle.

Just like how different musical notes can be played on different instruments, cubic harmonics can be played on different shapes of objects. Each shape has its own unique set of harmonic frequencies and wavelengths that determine the sound it produces.

So, if you hit a cube-shaped object and it makes a certain sound, that sound is a cubic harmonic. It's like the toy block is singing a song for you!
