who discovered that light is an electromagnetic wave
Electromagnetic radiation Maxwell derived a wave form of the electric and magnetic equations, thus uncovering the wave-like nature of electric and magnetic fields and their symmetry. Because the speed of EM waves predicted by the wave equation coincided with the measured speed of light, Maxwell concluded that light itself is an EM wave.[6][7][8] Maxwellâ€™s equations were confirmed by Heinrich Hertz through experiments with radio waves.
Ibn al-Haytham Alhazen showed through experiment that light travels in straight lines, and carried out various experiments with lenses, mirrors, refraction, and reflection.[49] His analyses of reflection and refraction considered the vertical and horizontal components of light rays separately.[50]
