|The distance measured perpendicular to the wavefront in the direction of propagation between two successive points in the wave separated by one period. Equals the ratio of the speed of sound in the medium of the fundamental frequency.
The table shows the wavelengths in air and water at a given freqeuncy.
Wavelength (m)=Speed of sound (m/sec) / Frequency (Hz):
The Speed of sound as a function of the temperature:
c=331,4 + 0.607 x t ( t is the temperature in degrees Celsius)
