Answer:
Explanation:
The amplitude of a sound wave is the measure of the height of the wave. ... It is the distance between crest or trough and the mean position of the wave. Loudness is directly proportional to the amplitude of the sound. If the amplitude of a sound wave is large, then the loudness of sound will be more.

frequency is The number of complete waves produced in one second is called frequency of the wave.
SI unit=Hertz
Amplitude is The maximum displacement of the particles of the medium from their original undisturbed positions, when a wave passes through the medium is called amplitude.
SI unit=meter
