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

true is the correct answer
