Question

The loudness of a sound decreases as we move away from a source of the sound. This is because _____.

  1. The frequency of sound decreases with increasing distance
  2. The frequency of sound increases with increasing distance
  3. The amplitude of sound decreases with increasing distance
  4. The amplitude of sound increases with increasing distance

hintHint:

Amplitude decreases indicates the decrease in loudness of the sound

The correct answer is: The amplitude of sound decreases with increasing distance


    • The loudness of a sound depends on the amplitude of the vibration producing the sound.
    • Therefore, the loudness of sound decreases as we move away from the source of the sound because the amplitude of sound decreases with increasing distance.
    • So, the correct option is c.
