# Wavelength Calculator

Formula: Wavelength(λ) = Velocity(v)Frequency(ƒ)

Default value of Speed of the Light in vacuum/air (v): 3 × 108 m/s

Enter the unknown value as ‘x’

Enter the Wavelength(λ): m

Enter the Frequency(ƒ): Hz or s1

x =

### What is Meant by the Wavelength?

In Physics, the wavelength is defined as the distance between two adjacent identical points in the waveform. It can be easily measured between two identifiable points such as crests or troughs in the waveform. The wavelength is inversely proportional to the frequency. The frequency refers to the number of wave cycles per second. The higher the frequency, the lower the wavelength, and vice versa. The wavelength can be determined using the frequency and wave speed. The formula to calculate the wavelength is given by

Wavelength = Velocity / Frequency.
