Question

What is the relationship between frequency and time period?

Answer 1

Frequency:

1. It is defined as the number of vibrations in 1 second.
2. Hertz (Hz) is the SI measurement unit of frequency.

Period:

1. Period is defined as the time taken for one complete vibration to pass through a given point. It is denoted by T.
2. The SI unit of the period is second.

Relationship between frequency and period:

1. Frequency is inversely proportional to the period or vice-versa.
2. Mathematically, we can see

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

3. As the period of a wave increases, its frequency decreases or vice-versa.
