Question

f) Define the term frequency. What is its S.I unit? What is the relation between

frequency and time period​

Answer 1

Answer:

Frequency is measured in hertz (HZ) which is equal to one occurrence a repeating  event per seceond. The period is the duration of time of one cycle in a repeating event , so the period is the reciprocal of the frequency.

The number of times a cycle is completed in a second is the frequency. The time taken to complete one vibration is called time period. Frequency and time period is inversely proportional, the number of vibrations per second is frequency. Relation between frequency f and time period T is f =1 / T.

Answer 2

Explanation:

The number of vibrations made by a particle of medium in one second is called the frequency of a wave.

The S.I unit of frequently is hertz (Hz)

Relation between frequency f and time period T is

f =1 / T.
