Question

Define the following term: (a) Amplitude (b) Time Period (c) Frequency (d) Phase

Answer 1

1. The maximum displacement of a vibrating body in a central position, is called Amplitude.
2. A vibrating body completes its one cycle, in a fixed interval of time. It is called Time Period.
3.A vibrating body completes its fixed number of cycles of vibration in one second, is called Frequency.
Hope it helps !

Answer 2

Amplitude :- The amplitude of a periodic variable is a measure of its change over a single period.

Basically the distance between the mean line and the wave.

Time period:- A time period (denoted by 'T' ) is the time needed for one complete cycle of vibration to pass in a given point.

It is also said to be T = 1/F

Frequency:- The number of times the wave is completed per unit time or every one second.

Phase:-Phase is the position of a point in time on a waveform cycle.
