Wavelength Calculator

Formula: Wavelength(λ) = Velocity(v) / Frequency(ƒ)
Default value of Speed of the Light in vaccum/air, Velocity(v) = 108 x 3 m/s.
A wavelength calculator is an online tool that helps to find the wavelength of a given frequency and velocity. It quickly calculates the relationship between wavelength and frequency.

What is Wavelength?

The distance between two waves can be referred to as wavelength. It can be calculated as the distance between two points of a wave.

Formula To Calculate Wavelength

Wavelength(λ) = Velocity(v) / Frequency(ƒ)


λ representes wavelength in meters (m),

v representes velocity in meters per second (m/s),

f representes frequency which is represented in hertz (Hz).

How to Calculate Wavelength?

To calculate the wavelength, you need the frequency and velocity of the wave.

  • Step 1: Take the formula for calculating the wavelength.
  • Step 2: Place the wavelength values, i.e. frequency and velocity, in the wavelength equation λ = v/f.
  • Step 3: Lastly, calculate the result.


Frequency = 120 Hz, velocity = 20,000 m/s, find the wavelength.


  • λ = 20,000/120
  • λ = 166.66 m.
  • The wavelength is 166.66 m.

How to Use the Wavelength Calculator ?

  1. Write the velocity or frequency in the given space.
  2. Click on the “Calculate” option to get the result.
  3. You can see the result on the screen.
