Detailed Solution

The above statement is false.
Frequency is the property that determines the shrillness or pitch of a sound. So, if the frequency of vibration is higher, then we can say that sound has a higher pitch; therefore pitch of a sound depends on the frequency of vibration. The higher the frequency, the higher the pitch, and the shriller the versa sound. The definition of the amplitude of a sound wave is given as “the loudness or maximum displacement of vibrating particles of the medium from their mean position when the sound is produced.” Therefore, we can say that the loudness of sound is determined by the amplitude of the vibration. A sound that is faint has a smaller amplitude, and a louder sound has a larger amplitude. Thus, it is false that the higher the amplitude of the vibration, the lesser the pitch.
