Resonance happens because two objects have the same natural what?

Resonance happens because two objects have the same natural what?

• A. Frequencies
• B. Wavelengths
• C. Amplitudes
• D. Interferences

Answer: (A)

Resonance happens when energy is transferred most efficiently because the driving motion shares the object's natural frequency—the rate at which it tends to vibrate if disturbed. When two objects have the same natural frequency, the forces act in sync with the motion, causing energy to accumulate and the oscillations to grow larger. This is why a system can respond with a much bigger amplitude under a matching drive than at other frequencies. Wavelengths describe spatial patterns and aren’t the trigger for resonance here; amplitudes are what you observe as the result of resonance, not the cause; and interference describes how waves combine, which can occur in many contexts but doesn’t by itself explain why resonance happens.
