The wave travels over the surface of the water at 32 mm s-¹. The diagram shows the wave pattern produced on the surface of the water. 7.0 mm S™¹ a. Calculate the frequency at which the waves will reach the edge of the puddle in front of the insect. b. Calculate the wavelength of the waves in front of the insect. C. At what speed, relative to the insect, do the waves travel behind the insect?
