← ScienceWhich outcome occurs when a piezoelectric transducer operates at acoustic resonance?
A)Increased energy conversion efficiency✓
B)Reduced signal-to-noise ratio
C)Decreased bandwidth for signal measurement
D)Limited maximum energy propagation
💡 Explanation
Increased conversion occurs through constructive wave interference because the acoustic resonance frequency creates maximum mechanical amplification via mechanical impedance matching. Therefore, efficiency increases, rather than reduced signal quality which could occur off-resonance.
