Moire effect is the result of 2 (or more I guess) similar regular, repeating patterns laid over each other but with a small delta.
Over a small section of the pattern, the patterns will mostly line up. But over a larger sections, you’ll see that some parts will over lap.
An example of this is would be to get 2 meshes. And place one mesh slightly behind the other.
You can hear the result too. A common way to tune a guitar relative to itself is to play one string open, and then play the same note on a different string. You’ll hear this beat that is not the note because the frequencies are close but not quite.
