Question 22

Two signal generators produce sound waves P and Q in a marine research tank. Wave P travels through water and then enters an acrylic observation window. In the acrylic, its speed is 2700 m/s and its wavelength is 1.5 m. Wave Q remains in water, where its speed is 1500 m/s and its wavelength is 0.50 m.

What is the ratio of the frequency produced by generator P to the frequency produced by generator Q?
