Use your knowledge of and experience with waves and to answer the following and show your work. What is the frequency in Hertz (Hz) of a signal that repeats 80,000 times in a minute? What is the period of the wave in part (a)? Now suppose you have a composite signal (composed of many frequencies). If the frequencies range from 50 Hz to 600 Hz, what is the (analog) bandwidth?

You hear a seal produce an alarm call on the beach. Some of this alarm sound will also penetrate into the water to alert seals swimming underwater. Based upon your measurements of acoustic impedance, you calculate that the Reflection Coefficient R=0.5. Please answer both parts of this question and show your work. 1. How much of the sound energy will reflect back from the water into the air? Give either the proportion or the percentage. If you give the percentage, you must include the percentage sign (%) 2. How much of the sound energy will penetrate into the water? Give either the proportion or the percentage. If you give the percentage, you must include the percentage sign (%)
