← ScienceWhich outcome results when standing waves induce material fatigue?
A)Resonant frequency causes mechanical resonance✓
B)Increased damping limits wave’s energy
C)Node displacement minimizes material stress
D)Acoustic impedance prevents standing waves
💡 Explanation
Mechanical resonance occurs because standing wave energy concentrates at resonant frequencies, magnifying oscillations. Fatigue increases, therefore resonance dramatically shortens component lifespan, rather than wave energy dissipating by damping that reduces vibration.
