Which feature of a sound wave is related to pitch?
a. amplitude
b. compressions
c. frequency
d. rarefactions

C. Frequency

Explanation:

As we know that the characteristics of sound is as following

1) Loudness : loudness of sound depends on the amplitude of sound so on increasing the loudness the amplitude will also increase.

2) Quality of sound : Quality of sound depends on the type of waveform. For different waveform the quality of sound is also different.

3) Pitch of sound : it depends on the frequency of the sound which means if the frequency of sound is more then its frequency will be more

So here correct answer will be

C). Frequency
