Wavelength to Frequency Calculator for Electromagnetic Waves in a Vacuum

WebThe equations impose no limits on wavelength or frequency. The only requirement is that they propagate with the speed of light in a vacuum. These conclusions were made in 1864 before there was any experimental evidence for invisible electromagnetic waves. Before Maxwell there was light and nothing else. WebMaxwell's equations may be combined to demonstrate how fluctuations in electromagnetic fields (waves) propagate at a constant speed in vacuum, c (299 792 458 m/s). Known as electromagnetic radiation, these waves occur at various wavelengths to produce a spectrum of radiation from radio waves to gamma rays. The equations have two major variants.
