Answer:
65m
Explanation:
Twelve waves pass a dock in 3.60 If the waves are traveling at 19.5 m/s , what is the wavelength of the waves?
Velocity of a wave is expressed as;
V = frequency × wavelength
Given
Velocity = 19.5m/s
Frequency is the number of oscillations completed in 1sec, hence
Frequency= 3.6/12
Frequency = 0.3
Wavelength = vel/freq
Wavelength = 19.5/0.3
Wavelength = 65m
