👉 rfz is a term used in the field of quantum mechanics, specifically describing the frequency of light waves that are emitted by atoms or molecules. These frequencies are typically considered as the fundamental energy levels of matter and can be described using the wave function, which represents the probability distribution of particles moving through space at different times. In quantum mechanics, the frequency of a photon (a unit of energy) is given by the Rydberg formula: \[ \nu = h \cdot n \cdot f \
