About this calculator
For any electromagnetic wave (radio, microwave, IR, visible, UV, X-ray), c = λν where c = 299,792,458 m/s. Visible light is 380-750 nm wavelength, equivalently 400-790 THz frequency. Red light has the longest wavelength (lowest frequency); violet has the shortest.
Frequently asked
