What type of wave was created? How do you know?

Estimate the wavelength of the wave produced.

Estimate the frequency of the wave produced. This is most easily estimated by counting the number of waves that pass the measuring device within a particular time interval as measured on your watch, or by counting the number of times the hand is shaken up and down.

Compute the velocity of your wave.
