The wavelength calculator is designed to evaluate the wavelength, wave velocity, and frequency of a wave. You can calculate any disturbance in a wave passing through a certain medium by using the calculator.

**“The wavelength is defined as the distance over which the entire shape of the wave repeats. This repetition happens after a fixed interval of time”**

The following equation may assist you in calculating the wavelength of a wave without trouble:

**λ = v/f**

Where;

**λ** = wavelength,

**v** = velocity of the wave,

**f** = frequency of the wave.

The number of waves per unit length is termed a wave number. It is always reciprocal to that of the wavelength. Every wave has its own specific wave number.

In order to determine the frequency-to-wavelength relationship, let us solve a few examples below:

Determine the wavelength of the light in space bearing a frequency of 3 Hz.

**Solution:**

The speed of light in a vacuum is given as:

**c = 300000000 m / s**

Using the wavelength frequency equation, we have:

**λ = v/f**

**λ = 300000000 / 3**

**λ = 100000000 m**

This requires a few inputs to calculate results with 100% accuracy.

Let’s have a look at these!

**Input:**

- Select the parameter you wish to calculate
- Input all the values against each parameter
- Click ‘Calculate’

**Output:**

- Wavelength and wave velocity
- Wave frequency and wave number
- Step-by-step frequency wavelength calculation

Amplitude is the maximum distance covered by a wave from its equilibrium position.

A wave in which the vibration of the medium is in the direction of the wave is called a longitudinal wave.

The direction of a transverse wave is always perpendicular to that of the medium in which it propagates.

Crests are the highest point of transverse waves whereas troughs are the lowest points.

For a longitudinal wave, the rarefactions and compressions are equal to crests and troughs for transverse waves.
