Velocity
The speed of matter waves depends sharply upon the medium, and in the case of a gas, its temperature and pressure. For instance, in air at 0°C and 1 atm pressure the speed is 331 meters/sec (mps) (730 miles/hr). In water and soft tissue it is 4 1 2 times higher than in air, and in solids it goes up to 5000 mps. The velocity of sound through fat is 1440, through muscle 1570, and through bone 3360 mps.
Velocity is independent of frequency; and it is probably just as well, otherwise the low tones of the organ might reach our ears later than the high tones of the same chord!
