Chapter 14, Problem 37A

To determine

The difference between frequency and time period.

Answer to Problem 37A

Frequency is the number of completed cycles per unit time where as the time period is the time taken to complete one cycle. When the object comes back from the extreme position to its initial position the cycle is counted to be one. The time taken to complete one such cycle is called time period and number of such cycles completed in per unit time is called frequency.

Explanation of Solution

Introduction:

Frequency is the number of cycles performed in given unit time. The unit of frequency is Hertz and denoted by $Hz$ . The formula of frequency is $f=\frac{1}{T}$ .

Period is the reciprocal of the frequency. It is the time taken to complete one complete cycle. It is given by $T=\frac{1}{f}$ .

Frequency is the number of all the complete waves which occur repeatedly in a unit time.

Frequency is denoted by $f$ .

  

Period is defined as the duration of time which is required by a wave to complete a unit cycle.

It is denoted by $T$ .

  

Conclusion:

Hence,frequency is the number of all the cycles of a wave which occurs in a given specific time. Time period is the time duration in which one complete cycle of wave is achieved.
