# 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 0.25 x hydrogen Air 0.25 x water Carbonic gas? 0.8 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
