Time Period :
(a) Time taken to complete one vibration is called time period.
(b) Time required to pass two consecutive compressions or rarefactions through a point is called time period.
• SI unit of time period is second (s). Time period is denoted by T.
• The frequency of a wave is the reciprocal of the time period.
V = 1/T
Amplitude :
The maximum displacement of the particle of the medium from their original undisturbed position is called amplitude of the wave.
• Amplitude is denoted by A and its SI unit is metre (m).
