Ääninopeuden
Ääninopeus, also known as the speed of sound, refers to the speed at which sound waves propagate through a medium. This speed is not a constant value and depends heavily on the properties of the medium itself. The primary factors influencing the speed of sound are the medium's elasticity and its density. In general, sound travels faster in more elastic materials because they are better able to restore their shape after being disturbed by a sound wave. Conversely, denser materials tend to slow down sound propagation because the particles are more resistant to displacement.
The speed of sound also varies with temperature. For gases like air, an increase in temperature leads
