Gold dredge for sale near meA wave has a frequency of 2000 Hz, determine its period. Therefore, the wave period is 0.0005 seconds. Formula to calculate wave period from wave length ( λ) and speed. We get wave period by dividing the wavelength by the wave speed. Example: Determine the wave period of a water wave whose length is 3m and its speed is 6 m/s.
