Higher frequency sound results in a ______ focus.

Explanation:
When we think about focusing sound, frequency determines the beam's wavelength. A higher frequency means a shorter wavelength, so the focusing device can produce a beam that stays narrow over a longer distance. That keeps the energy tightly concentrated deeper into the medium, giving a deeper focus. Of course, higher frequency also attenuates more quickly, which is a trade-off in real-world scenarios, but for the focusing behavior itself the trend is toward a deeper focal region.
