There isn't a "wave button" on an atomic clock. Atomic clocks are highly precise timekeeping devices that use the resonant frequency of atoms, typically cesium, to maintain accurate time.

They don't have buttons for user interaction like adjusting the time or setting alarms. Atomic clocks are primarily used for scientific research, timekeeping in communication networks, and other applications that require extremely accurate time measurements.

If you are referring to a specific device with a "wave button", please provide more context or information so I can understand what you are asking.
