Question

Please check the following statements for a longitudinal wave propagating from a medium with higher acoustic impedance (metal) to a medium with lower acoustic impedance (water) 7. 4 Points For oblique incidence the angle of reflection for the generated longitudinal wave is higher than the angle for the generated transverse (shear) wave If a Rayleigh wave propagates along to the surface of a metal block that is under water it is very likely that longitudinal waves are emitted into the water. If the angle of incidence for the longitudinal wave in metal is zero (normal incidence) then no sound is reflected. Only surface waves are generated. a. b. c. d.

Explanation / Answer

ANSWER:

A). For oblique incidence the angle of reflection for the generated longitudinal wave is higher than the

angle for the generated transverse (shear) wave.
