Wavelength to Frequency Calculator

If you are a curious physics enthusiast, then our wavelength to frequency calculator is your tool. Even if you aren't, you will find exciting information about frequencies and wavelengths. And we'll also help you understand how to calculate the wavelength of any frequency.

So keep on reading and have your curiosity satisfied.

A wavelength is the distance between adjacent crusts or adjacent troughs. It is the distance in which a wave completes its shape. As it measures the distance, its SI unit is meter.

Frequency is the measure of the number of waves per unit of time. Its SI unit is hertz (Hz). A wave with a high frequency has more energy, and a low-frequency wave has lower energy when measured at the same amplitude.

Our wavelength to frequency calculator is a time and energy-efficient tool that determines the frequency of a wave based on the wavelength. But that is not all; you can also input the frequency and estimate the wavelength. And if you still want more, we have got you covered because the calculator provides a list of wave velocities in different mediums, with the option to input a custom value for the velocity.

1. Look through the list of presets to locate your required wave and medium.
2. Selecting it will display its speed/velocity in the wave velocity section.
3. Input the wavelength in a unit of your choice.
4. The result is the frequency of the wave in Hz. You may select any unit to get your result.
5. If you want to enter a custom wave velocity, skip the selection of medium, and input the wave velocity directly.

For instance, the wave velocity is $89 \text { m/s}$, and the wavelength is $8 \text { m}$, then the frequency is $11.125 \text { Hz}$.

We also have a tool that determines a photon's energy based on its wavelength. Maybe you would like to check it out. It is wavelength to energy calculator.

If you are wondering,

• How to calculate the wavelength of a frequency? or
• How to calculate the frequency from wavelength?

Worry not, the formula is fairly simple. And you may be able to do it at your fingertips, but you don't really have to, our tool is here to rescue you. But let's still discuss the formula to enhance our knowledge.

$\lambda = v/f$

where:

• $\lambda$ = wavelength;
• $v$ = wave velocity; and
• $f$ = frequency.

This calculates the wavelength if you know the frequency and wave velocity. You may rearrange this formula to calculate the frequency from the wavelength.

$f = v/\lambda$

Let's look at an example.
Say the speed of sound in glass is $4540 \text { m/s}$, and the wavelength is $20 \text { m}$.
Place these values in the formula:

The wavelength of waves is interesting to know about, so these calculators might tickle your fancy.
