The wavelength of the vibrations produced on the surface of water is `2 cm`. If the wave velocity is `16 m//s`, calculate.
(a) the number of waves produced in `1 s`.
(b) time required to produce `I wave`.

Explanation

Here, wavelength of the wave, `lamda = 2 cm = 0.02 m`
wave length, `v = 16 m//s`
(a) number of waves produced in 1 s, i.e., `v = (v)/(lamda) = (16)/(0.02) = 800 Hz`.
(b) time required to produce 1 wave, i.e., `T = (1)/(v) = (1)/(800) s = 0.00125 s`.
