Resonance occurs when two objects share the same natural what?

Resonance occurs when two objects share the same natural what?

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

Answer: (A)

Resonance happens when a system is driven at its natural rate of oscillation. Every object that can vibrate has a natural frequency—how fast it tends to vibrate on its own. When a forcing source pushes at that exact frequency, energy is transferred very efficiently into the system, causing its vibrations to grow larger. That shared property between the two vibrating objects is frequency, so resonance occurs when they have the same natural frequency. Wavelength is about the spatial distance between wave crests and isn’t what governs resonance here. Amplitude describes how big the vibration is, but resonance is about matching the driving frequency to the natural frequency, not about having the same amplitude. Interference refers to how waves combine and is a different concept from the frequency-matching condition that drives resonance.
