One commonly used formula for waves is:
speed (of the wave) = frequency x wavelength
If you know any two of these pieces of information, you can calculate the third one.

A. speed=wevelength/weve period
frequency = (wave speed)/(wavelength) frequency = 1/(period)
draw a triangle and make 3 areas in the triangle. on the top is S or Speed. on the bottom left is F or Frequency. and on the bottom right is a bckwards/upside down Y for Wavelength. then S divided by For Y. and F times Y. will get you wavelength and what you need. draw what i just said.
The formula for a wave in this case is: speed = frequency x wavelength. Since Hz = 1/second, the answer will be in meter/second.
Both the wavelength and the frequency of a wave affect the speed of a wave.
