Question

A stone is thrown in a pond 12 full ripples are produced in 1 sec . If the distance between a crest and troughs is 10 cm calculate the wave length and velocity of wave

Answer 1

frequency of that wave is 12 Hz.
wavelength =
10 x 2 that is 20 cm.{20/100 metres}
we know that
velocity = frequency × wavelength.
velocity = 12 × 20/100
that is 240/100 m/s.
velocity = 2.4 m/s.
