4. A steel plate has been fused to an aluminum plate and immersed in a water bath. You have placed two transducers on either side of the metal plates so that the sound waves have to propagate from the first transducer through water, then through the aluminum plate, then through the steel plate, and finally through water in order to reach the second transducer. What percentage of the original acoustic energy reaches the second transducer
