The ability of an object to vibrate by absorbing energy at its natural frequency, which can cause a high-pitched sound, is called?

• A. Interference
• B. Absorption
• C. Resonance
• D. Refraction

Answer: (C)

Resonance is when an object absorbs energy most efficiently at its natural frequency, causing it to vibrate with a large amplitude and often a high-pitched sound. When you drive the object at that natural frequency, each energy input adds in step with the motion, building up the vibration over time rather than dying out. This is why a small periodic push or energy input can produce a strong, audible vibration at that specific frequency, like a tuning fork or a glass resonating. Interference involves how waves combine and affect each other, not the selective energy absorption at an object's own frequency. Absorption is about taking in energy generally but doesn’t by itself explain why the vibration grows at the natural frequency. Refraction is the bending of waves at a boundary between media. So the described ability is resonance.
