In a ripple tank, 10 ripples are produced per second. If the distance between a trough and a neighbouring crest is 12 cm, calculate the frequency, wavelength and velocity of the wave

Frequency = Number of ripples produced per second

That is,

Frequency, f = 10 Hz

The frequency of the wave is 10 Hz.

Wavelength, l = 2 × 12 cm = 24 cm = 0.24 m

The wavelength of the wave is 0.24 m.

Velocity of the wave = Frequency × wavelength

v = f × λ

   = 10 × 0.24

   = 2.4 m/s

The velocity of the wave is 2.4 m/s.
