A loud sound is heard when acoustic resonance takes place
Asked by lovemaan5500 | 1st Dec, 2017, 09:30: AM
Loudness is related to the amplitude of the sound wave.
At resonance frequency of the source matches with the natural frequency of the body
and they vibrate with maximum amplitude possible. Therefore, a loud sound is heard.

- A vibrating tuning fork is placed on a sonometer box and the distance between the bridges is adjusted until the paper rider in the middle of the wire (between the bridges) flies off. identify the forced vibration and resonance. explain briefly.
- why is the amplitude of forced vibration very small when the frequency of the external force is different from the natural frequency of the body?
