How, using a Ripple Tank with a Signal Generator attached to the Dipper, can you find the Frequency?

-First, get a Cork and Stopwatch -Then, make the Cork float in the Ripple Tank, and watch it Bob up and Down -When the Cork is at the Top of a Bob, start the Stopwatch -Record how many times the Cork Bobs in a given Time -Then Divide that Number by how Long you were Timing for, to get the Bobs per Second, also known as the Frequency.
