👉 Binodal is a term in physics that describes an object or system that has two or more modes of motion, such as vibration or oscillation. A binode is defined as a point where two or more frequencies are present, and it is often used to describe the resonance frequency of a system. In other words, a binode is a region of the spectrum where two or more frequencies overlap each other, creating an interference pattern that can be analyzed using spectroscopy techniques.
