Speed of em wave in vacuum
WebElectromagnetic waves travel at the same speed in a vacuum, which is the same speed as the speed of light (3 ⋅ 10 8 m/s). Electromagnetic waves can travel in a vacuum; therefore, they don ’ t need a medium to transmit. 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.
