Wave Speed Calculator


Table of Content


Our wave speed calculator calculates how quickly waves move through a medium by inputting values like wavelength and frequency. It's a handy tool to figure out how fast waves move in different situations, like in water or air.

Steps to Use Wave Speed Calculator:

Using a speed of wave calculator is easy and can help you find out how fast waves travel in different situations. Here, we'll guide you through the simple steps to make accurate calculations.

What to Enter?

  • Provide the values of frequency (f) and wavelength (λ)
  • Tap Calculate button

What will you Get?

  • Wave speed (v): know how fast a wave travels.
  • Wavenumber: 
  • Wave period (T): Get to know the time by which a wave completes its one cycle.
  • Measurements in various units: The tool gives you results in other related units of measurement so that you can understand calculations easily. 

The Expression of Wave Speed:

The wave speed formula provides a way to manually calculate the speed of a wave which includes:

Wave Speed (v) = fλ

In this speed of wave formula,

  • v = velocity
  • f = frequency
  • λ = wavelength

By using the above-mentioned equation, you can also determine the frequency and wavenumber of the traveling wave passing through a certain medium. 

How to Calculate Wave Speed?

To calculate wave speed, we will provide an example through which you can easily get assistance in getting the answer to how to find speed of a wave. You can also try a wave speed calculator for this.


Suppose you are sitting at the beach on a sunny day and watching the waves roll in. You notice that the waves follow a rhythm they come in groups, and there's a specific gap between each wave.

Let's have a look at how the speed of the waves works in this situation on the beach!

While sitting on the beach you decide to test the waves. You count how many waves pass a specific spot in one second, and you find that there are 5 waves. This measurement represents the frequency (f).

Next, you select a wave and measure its length from one peak to the next. You find that it spans a distance of 2 meters. This measurement represents the wavelength (λ).

Now, let's calculate the wave speed (v) using the formula:

Wave Speed (v) = fλ

Wave Speed (v) = 5 waves/second × 2 meters/wave

Wave Speed (v) = 10 meters per second (m/s)

So, in this real-life example, you have discovered that the wave speed at the beach is 10 meters per second. That means each wave travels at a speed of 10 meters per second as it reaches the shore.


Which wave has the highest speed?

In terms of speed, the wave with the highest speed is the electromagnetic wave. Electromagnetic waves travel in a vacuum at the speed of light, which is approximately 300,000 kilometers per second. This is the fastest speed that anything in the universe can travel.
