Question

Which of the following is false for loudness of sound and amplitude of vibration?


(A) Loudness of sound depends on its amplitude of the vibration.


(B) Loudness of a sound is proportional to the square of the amplitude of the vibration

producing the sound.


(C) When the amplitude of vibration is large, the sound produced is loud.


(D) If the amplitude of vibration is increased to 4 times of its initial value, then the

loudness of sound becomes 6 times of its initial value.​

Answer 1

Answer:

The amplitude of sound determines the loudness of sound. A sound that is faint will have a small amplitude while that of a loud sound will have larger amplitude. The Intensity wave is defined as the power delivered per unit area. Intensity of the wave is proportional to the square of amplitude of the wave.
