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. Sound waves are a common example of pressure waves, where vibrations in a source create alternating regions of high and low pressure that travel through air, water, or solids. Explosions and impacts also generate significant pressure waves that can travel considerable distances and cause damage. In fluid dynamics, pressure waves are crucial for understanding phenomena like shock waves, which occur when an object moves faster than the speed of sound in the surrounding medium, creating a supersonic pressure disturbance. Understanding pressure waves is essential in fields ranging from acoustics and seismology to engineering and medicine.
