Question

.we strike the drum lightly with its stick, we get a faint sound, but if we strike this with some

extra force, then we get a loud sound. The factor, which is responsible for producing the sound

of such different characteristics here, is

(a) frequency
(b) time period
(c) amplitude
(d) wavelength​

Answer 1

Answer:

Amplitude

Explanation:

A sound wave's amplitude relates to changes in pressure. The sound is perceived as louder if the amplitude increases, and softer if the amplitude decreases.

Loudness of sound is proportional to the square of amplitude. If the amplitude is tripled, the loudness increases by nine times.
