Question
The loudness of a sound decreases as we move away from a source of the sound. This is because _____.
- The frequency of sound decreases with increasing distance
- The frequency of sound increases with increasing distance
- The amplitude of sound decreases with increasing distance
- The amplitude of sound increases with increasing distance
Hint:
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.
