Explanation:
2.The amplitude of a wave refers to the maximum amount of displacement of a particle on the medium from its rest position.
3.Units-->Amplitude:metre(m)
Time period:second(s)

Answer:
sound waves generated by a sound source, such as the vibrating diaphragam of a stereo speaker. the sound source creates vibrations in the surrounding medium.
The maximum distance and displacement moved by a point on vibrating body or wave measured from its equilibrium position
The S.I unit of amplitude is meters. and time period is second
pitch is the rise and fall of our voice when we speak sometimes, called "highness or "lowness"
