Hint: When we play loud music then we feel our whole body is shaking that is nothing but vibrating at the resonance frequency, it makes another object also vibrate. This is what we know as resonance. In other words, resonance is the tendency of a system to oscillate with greater amplitude at some frequency than at others.
Complete answer:
The resonance happens when the frequency of the vibration of one body matches with the frequency of vibration of another body. Because of this reason the second body vibrates with resonant frequency due to the first vibrating body. The frequency at which the response amplitude is a relative maximum is known as system resonant frequency or resonance frequency. At these frequencies, even a small periodic driving force can produce large amplitude oscillations, because the system stores vibrational energy.
So, the loud music causes the air particles to vibrate and when we stand close to the source of loud music, it causes resonance and hence we feel our body shake or vibrate.
Additional information:
Resonance occurs when the body starts vibrating with greater amplitude when it experiences an external source of frequency very similar to its own natural frequency then it produces a loud sound.
Resonance phenomena obtain in all types of vibration or wave-like mechanical resonance, electrical resonance, and acoustic resonance.
The resonant system can be used to generate vibration of a specific frequency or take out
needed specific vibration from the complex vibration consisting of much different frequency.
Note:
Resonance is the maximum observed in a musical system when one string starts to vibrate while some other string is struck. This is also seen in an electrical circuit consisting of capacitors and inductors like the tuned circuits in radios and TVs.
