Notes
... A vibrating object can excite longitudinal waves in a surrounding medium, transmitting energy by sound. The velocity of sound in air is v = (331 + .6T) m/s where T is the air temperature in °C. Sound travels more quickly at higher temperatures and in denser media; sound cannot travel in a vacuum. Hu ...
