Define Following Terms Amplitude

Define the following terms : Amplitude, Time period, Frequency.


(a) Amplitude (A) : The maximum displacement of a wave on either side of its mean position is called Amplitude. A = XY is amplitude.
(b) Time Period (T) : Time taken to complete one vibration is called Time Period, i.e. from A to B

(c) Frequency (f) or u
Number of oscillations made by a wave in one second is known as its frequency.
