👉 The term "nondispersive" refers to a phenomenon where a wave or particle does not scatter when it passes through another medium, as in water. This property is important for many applications, such as sound waves in air, where the interference pattern of the wave can be used to detect and measure objects at great distances. Nondispersion is often described as "dispersion-free" or "dispersive," but this term could also refer to a phenomenon that does not scatter.
