Isofrequency refers to a condition in which two or more frequencies share the same intensity. Some synonyms for isofrequency include equifrequency, equi-amplitude, and uniform frequency. Equifrequency pertains to waves that have an equal or constant frequency within a specific wavelength. Equi-amplitude refers to waves that have equal amplitudes, which is the maximum displacement of a wave from its mean position. Uniform frequency, on the other hand, relates to signals that have a consistent, unvarying frequency level. These synonyms are useful in various fields like acoustics, laser optics, and telecommunications, where precise frequency control and calibration are essential.
