Frequency Calculator

This frequency calculator calculates the time it takes to complete one full cycle at the selected frequency and converts it to a period. A conversion scale for a variety of frequency versus time values will appear for each frequency entered.

Frequency Calculator: The frequency calculator will quickly calculate the frequency of a wave given its wavelength and velocity or period. You can select a wave velocity from a predefined list, eliminating the need to know, for example, the speed of sound. In the text below, you will also find the frequency definition, two frequency formulas (period to frequency and wavelength to frequency), and a few examples showing how to calculate frequency.

Frequency Definition and Formula

The number of completed wave cycles per second is known as frequency. In other words, frequency is the number of wave crests that pass through a certain spot in a second. The Frequency formula is given by: f = 1 / T


  • T stands for the time it takes to complete one wave cycle in seconds
  • f stands for frequency

What is the Frequency Calculator and How do I use it?

The following is how to utilise the Frequency calculator:

  • Enter the time it takes for one wave cycle to complete (period). The frequency will be determined by the calculator.
  • If you know the frequency, you can use this calculator to calculate the period.
  • If you need to compute frequency based on wavelength and wave velocity, use the following formula: f = 1 / T

Frequency Calculation Example

Question 1: How to calculate the frequency of a wave with a cycle time of 0.50s.


Consider the problem,

Time, T = 0:50s

The Frequency formula is given by: f = 1 / T

f = 1 / 0.50 s

f = 2 * 1/s

It's important to remember to convert "1/s" to the frequency unit:

f = 2 Hz

Therefore, The frequency of a wave is 2Hz

FAQs on Frequency Calculator

1. What is the pipes C value?

A factor or value used to describe the smoothness of a pipe's inside. The smoother the pipe, the bigger the carrying capacity, and the lower the friction or energy losses from water passing through it, the higher the C Factor.

2. How can I calculate wavelength using frequency?

  • Determine the wave's speed.
  • Select on a frequency.
  • Convert 1/s to Hertz.
  • Determine that the wave velocity and frequency are measured in the same time unit.
  • Divide the wave velocity by the frequency.

3. How do frequency and wavelength relate to each other?

Wave velocity divided by wavelength equals frequency. As a result, the lower the frequency, the longer the wavelength, and the higher the frequency, the shorter the wavelength. In other words, frequency and wavelength are inversely related.

4. What is the connection between frequency and power?

Frequency and energy are closely proportional. To put it another way, the higher the frequency, the more energy. The following formula for a photon's energy describes the link between frequency and energy.

5. What is the frequency of 5G?

The fifth-generation technology standard for cellular networks, 5G, operates on a variety of frequency bands that are divided into two frequency ranges.
