Wavelength is also measured<span> in meters (m) - it is a length after all. The frequency, f, of a </span>wave<span> is the number of </span>waves<span> passing a point in a certain time. We normally use a time of one second, so this gives frequency the unit hertz (Hz), since one hertz is equal to one </span>wave<span> per second.</span>
Determine the frequency and the speed of these waves. The wavelength is 8.6 meters and the period is 6.2 seconds. Now find speed using the v = f. λ equation<span>.</span>
