Two sources A and B vibrate with the same amplitude. They produce sounds of frequencies 1 kHz and 30 kHz respectively. Which of the two waves will have larger power?
The power of the sound wave is directly proportional to the Frequency.
∴ The sound wave having high frequency will have more energy.
⇒ Sound of Frequency 30 KHz has more energy than sound of 1 kHz.
