Question

Define:
1) Frequency
2) Timeperiod
e) Amplitude
​

Answer 1

Answer:

Frequency describes the number of waves that pass a fixed place in a given amount of time. So if the time it takes for a wave to pass is is 1/2 second, the frequency is 2 per second. ... The hertz measurement, abbreviated Hz, is the number of waves that pass by per second.

A time period (denoted by 'T' ) is the time taken for one complete cycle of vibration to pass a given point. As the frequency of a wave increases, the time period of the wave decreases. ... Frequency and time period are in a reciprocal relationship that can be expressed mathematically as: T = 1/f or as: f = 1/T.

Let's review. Amplitude is an important parameter of waves and is the maximum displacement of points on a wave. Stated another way, amplitude is the vertical distance between a peak or a valley and the equilibrium point. Frequency is the number of wave cycles passing a point per unit time.

Answer 2

★Answer★

Frequency

The number of such oscillations per unit time is the frequency of the sound wave.

Timeperiod

The time taken by two consecutive compressions or rarefactions to cross a fixed point is called the timeperiod of the wave.

Amplitude

It is defined as the maximum displacement produced in the vibrating particle on either aide of the mean position. It is denoted by A. Its Si unit is metre.
