Answer 2

a) amplitude- the maximum displacement of a vibrating body in a central position,is called amplitude.its SI unit is metre.

b) time period-a vibrating body completes its one cycle ,in a fixed interval of time . it is called time period. its SI unit is second.

c) frequency -a vibrating body completes its fixed number of cycles of vibration is one second,is called frequency.its SI unit is hertz.
