Which of the following statements is true the height of a wave determines the loudness of a sound or the higher the frequency of the sound the higher the pitch

Both the above statements are correct.

EXPLANATION:

The amplitude or the height of sound waves explains the effects of the sound and Amplitude is the "measure of intensity of the sound". Amplitude is the displacement of a particle from its mean position in either direction. This forms the "height of the sound wave" and thus the large value amplitude indicates more sound and a small value of amplitude results in less sound. If the frequency is "high than the sound" the "pitch will be higher" such that the sound with high frequency will have shrilling sound.For example, the "chirp of a bird" has a "higher pitch" as compared to the "roar of a lion".
