Question

A wave travels at 13m/s and the crests are 6 meters apart. what is the frequency of the wave?

Answer 1

To compute for the frequency of the wave, we must have its speed and wavelength. Wavelength is can be measured through the distance between two crests. Thus, the wave's wavelength is 6 m. And given that it travels at a speed of 13 m/s, we have


`f = (v)/(\lambda) \\ f = (13 m/s)/(6 m)`

Thus, we have
`f = 2.17 Hz`.

Answer: 2.17 Hz
