Question

how do loudness and pitch of sound depend on amplitude and frequency,respectively?

Answer 1

Higher the amplitude of sounder, louder the sound is and higher the frequency of sound waves, higher the pitch of the sound will be.

Answer 2

Amplitude is the maximum displacement of vibration so, large amplitude produces loud sound as larger vibrations produces louder sound.

Frequency of vibration determines the pitch of the sound thus the the large no. Of oscillation per sec. I.e.,frequency ,more pitch is the sound
