Question

natural frequency and resonance
which statement about resonance is correct?
○ resonance causes the amplitude of vibrations to decrease.
○ resonance does not affect the amplitude of vibrations.
○ resonance causes the amplitude of vibrations to increase.
○ resonance causes frequency to increase.

Explanation:

Resonance occurs when an oscillating system is driven by an external force at its natural frequency. This results in a transfer of energy that maximizes the amplitude of the system's vibrations, while the natural frequency of the system itself remains unchanged.

Answer:

Resonance causes the amplitude of vibrations to increase.
