Sonic instruments differ from ultrasonic instruments in which of the following?

Question

Quizplus · Accepted Answer

Sonic instruments operate at lower frequencies (typically below 6,000 Hz) compared to ultrasonic instruments, which operate at higher frequencies (above 20,000 Hz). This difference in frequency is the primary distinction between sonic and ultrasonic instruments. The motion of the tip, activated surfaces of the working end, and purpose of the water can be similar or vary based on the specific design of the instrument, but these are not the defining differences between sonic and ultrasonic instruments.
