Explanation:
Detailed explanation-1: -The frequency of a sound wave is equal to the vibration rate, and the intensity depends on the amplitude. These two characteristics of a wave are independent–that is, we can change either the frequency or the intensity of a wave without altering the other (see Fig.
Detailed explanation-2: -Loudness: The phenomenon of sound waves that depend on the amplitude and energy of the sound wave is called Loudness.
