Link and Zelda are at the beach. Link is standing on the shore and Zelda is doing some underwater swimming. They both hear a boat that is 3,200 m (2 miles) away. They are both able to measure the frequency and wavelength of the sound wave they hear. What is a possible frequency and wavelength that Zelda could report? It is a very sunny day and both the water and air are at 20 degrees Celsius.
