Wavelength to Frequency Converter

This converter makes it possible to transform a wavelength λ into the corresponding frequency f. Wavelength is the distance a wave travels in one complete cycle, while frequency indicates how many cycles occur per second. This converter is useful for RF, optical and telecommunications engineers to determine the frequency from the measured wavelength.

Formula

f = c / λ

Explanation of the formula

The frequency f (in Hertz) is obtained by dividing the speed of light c (≈ 299,792,458 m/s) by the wavelength λ (in meters). The shorter the wavelength, the higher the frequency, and vice versa. The formula can be adapted to obtain the frequency in MHz or GHz depending on the desired output unit.

Uses

  • Determination of the frequency of a radio, microwave or optical signal from its wavelength.
  • Planning of communication systems and design of antennas.
  • Spectral analysis in RF and optical applications.
  • Quick conversion between different wavelength and frequency units for technical documentation or measurement reports.
