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 (%)
