While observing the waves, we can see that phase changes with respect to time. The difference between any two points in the same phase is called as Wavelength. Wavelength is denoted by $\lambda$.
Wavelength Calculator or Frequency Wavelength Calculator will help us to calculate the wavelength, when frequency(f) is given and also used to calculate frequency(f), when wavelength($\lambda$) is given. The default value of the speed of the light in air/vacuum is given by 3 $\times$ 108 m/s. Wavelength Frequency Calculator will use the following formula:
The Formula for Wavelength is given by the equation:
$\lambda$ = $\frac{v}{f}$ or $f$ = $\frac{v}{\lambda}$
where
$\lambda$ = Wavelength in m
$v$ = Speed of the wave in m/s
$f$ = frequency of the wave in Hz or s-1

## How to Calculate Wavelength?

Step 1 :

Wavelength Formula:

Wavelength($\lambda$) = $\frac{Velocity(v)}{Frequency(f)}$

Frequency(F) = $\frac{Velocity(v)}{Wavelength(\lambda)}$

where
$\lambda$ = Wavelength in m
$v$ = Speed of the wave in m/s
$f$ = frequency of the wave in Hz or s-1

Step 2 :

State the equation you plan to use and plug in the values.

## Problems on Wavelength Calculator

1. ### The light wave moves with the frequency 50Hz, then calculate its wavelength?

Step 1 :

Given that:

Frequency of the wave(f) = 50Hz

We know that Velocity of the light = 3 $\times$ 108

Wavelength($\lambda$) = ?

Step 2 :

We know that:

Wavelength($\lambda$) = $\frac{Velocity(v)}{Frequency(f)}$

Wavelength($\lambda$) = $\frac{3 \times 10^{8}}{50}$

Wavelength($\lambda$) = 6000000 m

Wavelength($\lambda$) = 6000000 m

2. ### If the light has a wevelength of 500m, then calculate its frequency?

Step 1 :

Given that:

Frequency of the wave(f) = ?

We know that Velocity of the light = 3 $\times$ 108

Wavelength($\lambda$) = 500 m

Step 2 :

We know that:

Frequency(F) = $\frac{Velocity(v)}{Wavelength(\lambda)}$

Frequency(F) = $\frac{3 \times 10^{8}}{500}$

Frequency(F) = 600000 Hz
