Question

what do you understand by frequency and time period? establish relation between them​

Answer 1

Answer:

Frequency is the number of occurrences of a repeating event per unit of time. ... Frequency is measured in units of hertz (Hz) which is equal to one occurrence of a repeating event per second. The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency.

Answer 2

Frequency and time period can be defined as follows:-

• Frequency- It is the number of waves that cross through a fixed area in a particular interval of time. SI unit of frequency is Hertz(Hz).
• Time period- The time taken by a wave to complete one cycle of vibration is called its time period. It is measured in seconds(s)

Relation between frequency and time period is:-

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

where f stands for frequency and T stands for time interval. Therefore, the greater the time period of a wave, the lower is its frequency.
