Which of the following will NOT cause a redirection of part of the ultrasound energy?

Explanation:
When ultrasound energy travels, redirection happens through processes that send energy off the original forward path. Reflection sends energy back toward the transducer, scattering sends energy in many directions because of tissue microstructure, and divergence causes the beam to spread, moving energy away from the central axis. Absorption, on the other hand, reduces energy by turning it into heat within the tissue along the path rather than sending it in a different direction. So absorption does not redirect energy; it attenuates it without changing its direction.
