Answer:
Since the wavelength is inversely proportional to the frequency, the wavelength will decrease when the frequency increases, resulting in higher tones. The amplitude is perceived as the loudness of sound.
Step-by-step explanation:
Sounds are determined by how an object vibrates. Sound waves travel at the same speed but vibrate in different ways. Some vibrate quickly and have a high frequency or pitch, while others vibrate slowly and give a lower pitch.
