Ripples in a pond travel at a velocity of 3 m/s with one peak passing a reed near the shore every 0.25 seconds. What is the wavelength of the ripples? What is their frequency?
Homework Answers
speed, v = 3m/s
time period = time between two peaks, T= 0.25 sec
now wavelength = v ×T = 3 ×0.25 = 0.75 m
frequency, f =1/T = 1/0.25 = 4 Hz
