What does resonance refer to in the context of sound?

1. Echoing of sound waves

2. Vibratory response to a frequency

3. Absorption of sound

4. Sound produced by friction

The correct answer is: Vibratory response to a frequency

Resonance refers to the phenomenon where a system vibrates with a higher amplitude at specific frequencies, known as resonant frequencies. In the context of sound, when an object or system is exposed to a sound wave that matches its natural frequency, it responds by vibrating more intensely. This increased vibration can amplify the sound, creating a richer and fuller tone. This is often observed in musical instruments, where the body of a guitar or the sounding board of a piano resonates to enhance the sound produced by the strings. Understanding resonance is crucial in fields like acoustics and music, as it influences sound quality and volume.
