About Wavelength & Frequency Conversion

Wavelength and frequency are inversely related through the speed of light: c = λf, where c ≈ 299,792,458 m/s. Visible light spans roughly 380-700 nm (430-790 THz). Radio waves range from kHz to GHz frequencies with wavelengths from kilometers to millimeters.

This converter works across the entire electromagnetic spectrum, from radio waves to gamma rays, converting between any wavelength or frequency unit.
