Suppose a wave has a wavelength of 2 meters and frequency of 2 Hertz then the velocity is 4 meter per second. The derived unit of frequency is hertz Hz. One method for measuring the speed of a ripple on a water surface is to use a large calm pond or lake.
Calculating Wavelength Given Speed and Frequency 1.
For aluminium E 70 x 10 10 Nm -2 and 27 x 10 3 kg m -3. The sine wave is a specific case of a periodic wave. One person counts down from three and then disturbs the water surface using their hand for example to create a ripple. It is calculated by dividing the distance travelled by the time taken.
