Solution

(a)Amplitude (A) : The maximum displacement of a wave on either side of its mean position is called
Amplitude A = XY = is amplitude.
(b) Frequency (f) or n
Number of oscillations made by a wave in one second is known as its frequency.
(c) Time Period (T): Time taken to complete one vibration is called Time Period,
