# Wavelength to Frequency Calculator

The Wavelength to frequency calculator is the best tool to calculate the wavelength or frequency for the given parameters. All you have to do is give the parameters and click on the calculate button to get the answers in a fraction of seconds.

### What is Wavelength to Frequency?

Wavelength is the gap between the two troughs and crests of the wave. wavelength is indicated by the symbol 'λ'. The frequency will be defined as the no. of times a recurring occurs in a second. Units of frequency are Hz or Hertz. wavelength to frequency formula is given below.

Wavelength = (Speed) / (frequency)

We will see the symbolic representation of this formula is,

λ=c / f

If the frequency is low, then the wavelength will be high.

### How to Find the Wavelength to Frequency?

By following the guidelines you need to find the wavelength to frequency.

- Firstly, write all the values which are given in the problem.
- Then, write the formula, λ=c / f.
- And get the desired answer.

### Example Question for Wavelength to Frequency

**Example Question: For the light ray, the wavelength is equal to 250nm. Find the frequency of the ray.**

**Solution:**

Given data wavelength(λ) = 250nm = 250 x 10^{-9}

As we, already now that, C = 3 x 10^{8}ms^{-1}

Now, we will see the formula.

λ = c / f

Rewrite the formula, as we know the values of wavelength and speed, we need to find the frequency.

F = c / λ

= 3×10^{8} / 250×10^{-9}

F = 1.19916983 MHz.
