Which statement below BEST describes the consequence of damping material?

The process of making the impedance values on either side of a boundary as close as possible to reduce reflections is called:

The impedance of a xdcr’s matching layer is 2.6 MRayls and the impedance of the piezoelectric crystal is 3.4 MRayls. If this is assumed to be a good imaging system, what is the best estimate for the impedance of the skin?

The graph of the function f(x) is shown below.  

The piezoelectric crystal transforms:
