A wave equation is an equation that repeats y-values infinately creating a wave like pattern, a good example is the sine wave: http://en.wikipedia.org/wiki/Sine_wave
Scroll down to related links and look at "Wave equation - Wikipedia".
Wave speed wavelength times frequency.
v = f
speed
frequency
frequency for apex learners not speed :)
Here is an equation that relates three quantities of any wave: speed = frequency x wavelength. However, I am pretty sure that usually, you'll have to somehow measure the speed of the wave, instead of calculating it. In other words, you would measure the speed and the frequency, and then use the formula to calculate the wavelength; or measure the speed and wavelength, and use the formula to calculate the frequency.
That would depend what information is available. One common equation is: speed = wavelength x frequency. However, in a practical situation, it may be easier to actually measure the wavelength and (for example) the frequency, and then make deductions about the wavelength, than the other way round.
Since the speed of the wave is equal to the wavelength times the frequency, all you need to do is divide the speed by the wavelength in this case.
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.
The speed or velocity of a wave is equal to the wavelength times the frequency. The period (amount of time for one wavelength to occur) is equal to 1 over the frequency (the inverse of its frequency).

Wave speed wavelength times frequency.
The product of (wavelength) times (frequency) is equal to the speed of the wave.

Divide the speed by the wavelength. (For any wave, the wavelength times the frequency is equal to the speed of the wave.)
Since the speed of the wave is equal to the wavelength times the frequency, all you need to do is divide the speed by the wavelength in this case.
(wavelength) x (frequency) = wave speed
