The wavelength of waves produced on the surface of water is 20cm. If the wave velocity is 24m/s, calculate (i) the number of waves produced in one second and (ii) the time in which one wave is produced.
The wavelength of waves produced on the surface of water is 20cm. If the wave velocity is 24m/s, calculate (i) the number of waves produced in one second and (ii) the time in which one wave is produced.

(i)The frequency or number of waves produced per second

= wavelength / velocity

=\(\frac{24}{20}\times {{10}^{-2}}\)

=120

(ii) Time it takes for one wave to form = 1 / frequency

= 1/120

= \(8.3\times {{10}^{-3}}\) seconds
