How to Calculate Wavelength?

Along with the wavelength tool, there are a set of step-by-step procedures involved in calculating the wavelength. Using the formula, one can substitute the variables with their respective numerical values, the manner in which will be listed below along with the formula to make it easier for viewers to understand how and why the formula represents the wavelength. Here find in the following sections the steps to solve a wavelength-related question.

  • First of all, determine the frequency of the wave and its type.
  • Choose the velocity of the wave.
  • Substitute the numerical values of the above into the wavelength equation.
  • Find the result using the mathematical calculation involved in this equation.
  • Utilize our calculator as a tool to save time and get a more accurate answer.

The list above is indicative of the steps involved in a mathematical equation.

Wavelength Formula

The wavelength formula is encapsulated within the following equation

𝛌 = v/f

The above-mentioned formula depicts the mathematical relationship between wavelength and frequency. If one can notice, this formula is also a representation of how all three properties of waves are incorporated to justify the relationship between waves and frequencies. To make sure the problem you are solving is in line with the question when measuring using this formula keep in mind the respective units of measurement of all the variables given.


Question: Find the value of the wavelength if the frequency of radio waves is given as f = 10 MHz?


First use the formula: 𝛌 = v/f

Input the value of velocity of the wave v = 299,792,458 m/s

Input the value of the frequency, which is 10.

The equation becomes: 𝛌 = 299792458 / 10

The result becomes: 𝛌 = 29.98 m

This is the wavelength.

Frequently Asked Questions on Wavelength

1.What is wavelength?

Wavelength, a physics concept, is the distance measured between the corresponding points of two waves. It is less related to the other concepts of physics as much as it is connected to the physical concept of light.

2. What are the properties of wavelength?

The concept of wave is a broad concept which primarily consists of three major properties: wave velocity, wavelength, and frequency. Since the concept of wave is so broad, these three properties subdivide and attempt to describe what a wave really is and how it functions.

3. What are the typical wave speeds?

Typical wave speed is the speed at which a wave passes through a medium. The following are common mediums which waves pass through.

  • Light in air/vacuum = 299,792,458 m/s
  • Light in water = 224,901,000 m/s
  • Sound in air = 343.2 m/s
  • Sound in water (20 degrees Celsius) = 1,481 m/s


4. What is the formula for wavelength?

This formula denotes the entire relationship between a wavelength and its velocity and frequency 𝛌 = v/f

5. How to use this wavelength calculator?

One can either choose to find the wavelength through manual workings and equation-solving techniques, those who choose to use the wavelength calculator cut through the hassle. This online free calculator is designed to provide an easy-to-use interface which allows individuals to type in the numerical values and find the answer to a wave-length related question.
