Answer:

a)Amplitude - The maximum displacement of a wave on either side of its mean position is called Amplitude.

(b) Frequency - Number of oscillations made by a wave in one second is known as frequency.

(c) Time period - Time taken to complete one vibration is called time period, i.e. from A to B.
