Question

40 wave pass through a point on the surface of a pondin 2 second. calculate the wavelength if the velocity of wave is 3.5 ms?​

Answer 1

Answer:

waves passing in the surface in 1 second is 40/2=20 waves => frequency

velocity= frequency × wavelength

3.5= 20 × wavelength

wavelength. = 3.5/20 => 0.175m/s
