Higher frequency beam will

Explanation:
Higher frequency waves are attenuated more rapidly when they pass through tissue, so they deposit energy in the nearer, superficial layers rather than traveling deep. This increased attenuation means the beam is absorbed sooner, converting more of its energy to heat in the surface regions. Higher frequency thus gives shallower heating, while lower frequency would penetrate deeper because it loses energy more slowly. Reflection isn’t the defining outcome of higher frequency, and there will always be some interaction with tissue, so the option describing absorption sooner best fits the behavior.
