#Count Adjust the number of [[wavefrequency]]s that pass a given point over 10 of the [[secondoscillator]]s.#Divide the number of until it produces a clear [[wave]]s by on the 10 [[second]]s to find string.#Record the [[frequency]] of the [[waveoscillator]]s.#[[Measure]] the length [[wavelength]] of the [[Ripple Tank|ripple tankwave]] from paddle to end using a [[ruler]].#Use a [[stopwatch]] to [[time]] how long it takes for a [[wave]] to travel this [[displacement]].#Use the equation <math>v=f \frac{s}{t}lambda</math> to find the [[velocityWave Speed|wavespeed]] of the [[wave]].#Use the equation <math>v=f \lambda</math> to find the Repeat for different 5 [[wavelengthfrequency|frequencies]] of the [[wave]].

: Counting the number of [[wave]]s over a greater period of [[time]] greater than 10 [[second]]s will create Calculate an [[Mean Average|average]] of for the [[frequencyWave Speed|wave speed]] over a greater number of [[results]] to give a more [[waveprecise]]s and therefore increasing number by reducing the [[precisionuncertainty]].
