a). The maximum displacement of a vibrating particle from its rest (or mean) position is called its amplitude. It is expressed in the metre. b). Frequency and time period are interrelated. Frequency is measured in s - 1 . c). The loudness of a sound depends on the amplitude of vibration of the vibrating body producing sound. Greater the amplitude, louder is the sound produced. d). A high pitch sound corresponds to a high-frequency sound wave and a low pitch sound corresponds to a low-frequency sound wave. e). Wave form determines the quality of sound. Wave form comprises many frequencies.
