the wave length of vibration produced on surface of water is 2cm if the wave velocity is 16m/s find frequency and Time period
use velocity = frequency x wavelength
and Time period = 1 / Frequency

solution:
The formula for energy is 1/2mv^2
According to question:
1/2m(V2^2 - V1^2) = n x 1/2mV^2
=> n = (V2^2 - V1^2) / V^2
=> n = (400 - 100) / 100
=> n = 3
Hope it helps!
