Which outcome occurs when a piezoelectric sensor rapidly oscillates?

💡 Explanation

Oscillation generates ultrasound because the piezoelectric effect causes continuous expansion/contraction when stimulated with alternating voltage, therefore ultrasonic waves are emitted, rather than increased capacitance, due to constant charge balancing at resonance frequency.
