# Frequency Calculator

If you want to determine the frequency of a wave, you can immediately use our frequency calculator.

In physics, the amount of cycles exerted by a wave in a second is known as frequency. In other words, it can be defined as the number of waves that move a certain point in a unit of timeFrequency is defined as the inverse of a period, whereas the period is the time taken by a wave to complete one cycle. The SI unit used for frequency is Hertz (Hz).

## Formula of Frequency Calculator

To calculate the period of a wave manually, you can use the formula listed below; Or, to find it instantly, you can jump to our frequency calculator.

f = 1 / T

Where,

f = Frequency of a wave

T = Time taken by a wave to complete its cycle

Note:

To calculate relative frequency, you can use our Relative Frequency Calculator.

### Example

To determine how to calculate the frequency of a wave, let's have an example below:

Suppose a wave moving in an ideal situation, completed its one cycle in 0.25s, find out the frequency accomplished by a wave.

Given data

T = time = 0.25s

To Find

Frequency of a wave = ?

Solution

To find out the frequency of a wave, we will use the formula listed below:

f = 1 / T

Putting values in the formula:

f = 1 / 0.25s = 4 Hz

### How to use the Frequency Calculator?

The steps to use the frequency calculator are as follows:

Step 1: Enter the value of time in the first required input.

Step 2: The calculator will automatically display an answer on the screen.

### Calculator use

You can use our frequency calculator for various oscillatory principles, such as mechanical vibrations, radio waves, the sound of an object, etc.
