helilainest
Helilaine is a term used in acoustics and physics to describe a disturbance that propagates through a medium, such as air, water, or solids, as a wave of pressure variations. These variations are caused by the vibration of particles in the medium. When a source vibrates, it displaces the surrounding particles, which then collide with adjacent particles, transferring energy and causing them to vibrate as well. This chain reaction propagates outwards from the source, forming a wave.
The speed at which a helilaine travels depends on the properties of the medium, such as its
The amplitude of a helilaine is related to the intensity of the sound, which is perceived as
