<p>The speed of an acoustic wave depends on the properties of the medium it travels through and on temperature; for example, it travels at approximately 343 meters per second in air, and 1480 meters per second in water. Acoustic waves encompass a broad range of phenomena, from audible sound to seismic waves and ultrasound, finding applications in diverse fields like <a href="page.php?w=acoustics">acoustics</a>, <a href="page.php?w=engineering">engineering</a>, and <a href="page.php?w=medicine">medicine</a>.</p>
