3. Two boats are anchored 12.13 m apart. As a series of waves passes, the boats float up and down but when one is up, the other is always down. What wavelength wave could produce this effect?
4. A classmate of yours, 1000 m away, strikes a railroad track which you have your ear on. How long after he strikes will the sound arrive? Assuming that the speed of sound on steel is 5.00 × 103 m/s, what is its wavelength? 5. Busa girl is 8.0 m away from a source of sound. While, Tubu boy is 4.0 m from the same source. What is the ratio of sound intensity heard by Tubu boy to that of Busa girl?
