Unformatted text preview: A i K A o z x A plane harmonic acoustic wave of frequency at an angle is incident on the plate surface from the water halfspace as illustrated in the diagram above with pressure amplitude of A i . The reflected wave has amplitude of A o . 1 (a) Derive an expression for A o in terms of A i , , , c, K and . (b) Investigate asymptotic behavior of the expression derived in (a) as the following approaches limits: i. Stiffness of the elastic foundation, K ii. Frequency of wave, Discuss the physical meaning of any asymptote that arises. 2...
