👉 In physics, a "vacillator" is a hypothetical particle that possesses both wave-like and particle-like characteristics. They are often used to model quantum systems such as electrons in atoms or photons in light waves. In these situations, they can exhibit superpositions of states, which could be described by wave functions.
Vacillations are the most common kind of vacillator, where a particle oscillates between two energy levels without settling into a specific state. This property is analogous to a quantum mechanical particle moving
