👉 The term "extramodal" is a term used in physics and engineering to describe phenomena that occur at different frequencies compared to other frequencies. In physics, an extramodal phenomenon occurs when there are two or more physical processes occurring simultaneously at different frequencies. This can happen for example in the case of a sound wave, where the same frequency of sound waves are being generated by different sources. In engineering and technology, extramodal phenomena can be used to improve the performance of systems, such
