Question

Philoid · Accepted Answer

In the first case in which the string is plucked in the middle produce a louder sound because:

⇒ The loudness of a sound depends upon the amplitude of vibration.

⇒ Greater force means greater amplitude.

⇒ This means, when the string is plucked with greater force, the amplitude of a string is larger.

⇒ Thus, the sound will be louder in this case.
