Which outcome occurs when ultrasonic transducer operating frequency nears fluid's cavitation threshold?

💡 Explanation

When an ultrasonic transducer's operating frequency approaches the fluid's cavitation threshold, inertial cavitation occurs because bubbles form and collapse rapidly, scattering and attenuating the transmitted signal. Therefore, increased signal scattering results, rather than enhanced resolution, lower thermal load, or impedance matching improvements, which demand different wave characteristics or stable conditions.
