Nyomáshullámnak
Nyomáshullámnak, which translates to "pressure wave" in English, refers to a disturbance that propagates through a medium, causing temporary changes in pressure. These changes then travel outward from the source of the disturbance. The speed at which a pressure wave travels depends on the properties of the medium it is passing through, such as its density and elasticity.
Pressure waves are a fundamental concept in physics and are responsible for a wide range of phenomena.
