Velocity of Sound

Velocity = Frequency X WaveLength
Velocity of sound in air varies greatly with temperature. The velocity at any temperature can be found adding 1 foot for a degree of Fahrenheit increase.

Air = Unity or 1083 ft per second @ sea level
Water 4 x air
Hydrogen 4 x oxygen
Oxygen .25 x hydrogen
Air .25 x water
Carbonic gas .8 x air
Coal gas 1.6 x air
Hydrogen 3.56 x air
Brass 10.86 x air or 11480 fps
Steel 15.34 x air or 16410 fps
Glass 15.25 x air
Copper 11.96 x air or 11.17 or 11.96 or 11670 fps
Steel wire 15.108 n or 15.34
