Sample C would be best, because the percentage of the energy
in an
incident wave that remains in a reflected wave from this material

The coefficient of absorption is the percentage of incident sound
that's absorbed. So the highest coefficient of absorption results in
the smallest </span><span>percentage of the energy in an
incident wave that remains.
That's what you want. </span>
