The wave base (the depth at which water moves) would be about 10 feet, or 1/2 the wavelength.
We think of a sound in air. Speed of sound c = 343 meters per second at 20 degrees Celsius or 68 degrees Fahrenheit. The Frequency f = speed of sound c divided by wavelength lambda. Frequency f = 343 / 0.2 = 1715 Hz. The period of time T = 1 / f, that is 1 / 1715 = 0.0005831 seconds = 0.5831 milliseconds.

Frequency = (speed)/(wavelength) = 20/2 = 10 Hz
Wave speed = (frequency) x (wavelength) = (50) x (20) = 1,000 meters.
Wavelength = (speed) divided by (frequency) = 10/0.5 = 20
Frequency = (speed)/(wavelength) = 10/20 = 1/2
340 m/s
Convert the cm to meters, to have compatible units. Then use the fact that the frequency times the wavelength is equal to the speed of the wave. In this case, you can divide the speed by the wavelength, to get the frequency.
To find the wavelength, the following formula applies: λ = ν / f That in common words is: Wavelength = Wave's Speed / Wave's Frequency So, Wavelength of sound wave = Speed of sound wave / Frequency of sound wave Now, Speed of sound wave is 343 m/s, so Wavelength of sound wave = 343 m/s / Frequency of sound wave Frequency of sound waves audible to a human ear range between 20 Hz to 20 kHz. So filling the desired sound frequency in the equation above you get the desired wavelength of that sound wave.
wave velocity = frequency in Hz x wavelength in meterSo frequency = 5 Hz and wavelength = distance between successive peaks = 20 cm = 20/100 mHence wave velocity = 5 * 20/100 = 1 m/s
Divide the speed by the frequency
Wave speed c = frequency f times wavelength lambdaFor a wave in air the speed of sound is c = 343 meters per second at 20 degrees Celsius.For a wave in vacuum the speed of light is c = 299 792 458 meters per second.frequency f = wave speed c divided by wavelength lambda.There is a useful calculator for converting wavelength to frequency and vice versa.Scroll down to related links and look at "Acoustic waves or sound waves in air".
Use the fact that the frequency, multiplied by the wavelength, is equal to the speed of a wave. In a vacuum, light will move at 300 million meters/second; just divide this speed by the frequency.
(frequency) multiplied by (wavelength) = (wave speed)
