How does the amplitude of a wave affect sound? A. Higher the amplitude the louder the sound b. Lower the amplitude the louder the sound c. Higher the amplitude the higher the pitch d. Lower the amplitude the higher the pitch

Answer 1

A. Higher the amplitude the louder the sound

The amplitude of a wave determines the loudness or volume of a sound. A higher amplitude corresponds to a louder sound, while a lower amplitude corresponds to a quieter sound. Pitch, on the other hand, is determined by the frequency of the wave, not its amplitude.
