Wind gusts create ripples on the ocean that have a wavelength of 5.00 cm and propagate at 2.00 m/s. What is their frequency?

This is College Physics Answers with Shaun Dychko. Wave speed is frequency multiplied by wave length. So to solve for frequency we divide both sides by lambda. So f equals v over lambda and that is two meters per second divided by five centimeters written as five times ten to the minus two meters. This gives a frequency of 40 Hertz.
