n a ripple tank of length 1.6 m, waves cover this length in 2 seconds. If the distance between two consecutive troughs is 20 cm, find the number of waves, the frequency of the waves, and their time period.
Waves in a ripple tank: Given: Length of the tank L=1.6 m Time t=2 s Distance between consecutive troughs (wavelength) λ=20 cm=0.2 m The number of waves N can be found as: N=L/λ=1.6/0.2=8 The frequency f is: f=N/t=8/2=4 Hz The time period T is: T=1/f=1/4=0.25 s Related Questions: A simple pendulum has a time period of 2 s. It is called a … Read more
