Question

Which of the following is true about the relationship between the amplitude of sound waves and the intensity of sound?
a. Sound intensity is high if the amplitude is low.
b. The greater the amplitude, the greater the intensity of the sound.
c. The intensity of the sound is low if the amplitude is high.

Answer 1

Answer:

The sound is perceived as louder if the amplitude increases, and softer if the amplitude decreases. ... As the amplitude of the sound wave increases, the intensity of the sound increases. Sounds with higher intensities are perceived to be louder. Relative sound intensities are often given in units named decibels (dB).
