What is the Light wave in details [Explained]

Light waves are electromagnetic radiation generated by electrons in the process of atomic motion. The movement of electrons in atoms of various substances is different, so the light waves they emit are also different. Spectrum is a pattern of monochromatic light separated by a dispersion system (... Read More
