Answer to Question #181851 in Physics for John

Question

A vibration can be described in terms of 

 

(i)​The period

(ii)​The frequency

(iii)​The amplitude

 

Define each of the terms listed above and note any relationship between them.

Answer 1

1. By definition, the period is the time required to make one oscillation.

2. The frequency is the number of oscillations per second.

3. The amplitude is the maximum absolute value of signal.

The relation between the period $T$ and frequency $f$ is the following:

$$f = \dfrac{1}{T}\\ T = \dfrac{1}{f}$$

The amplitude depends neither on period nor on frequency.
