The electromagnetic spectrum is distributing electromagnetic radiations based on their frequency or wavelength, known as the electromagnetic spectrum, that is, distributing electromagnetic radiations based on frequency or wavelength based on frequency or wavelength. is done. Strips of electromagnetic radiation are formed which are called the electromagnetic spectrum. The electromagnetic spectrum of various electromagnetic waves is shown in the figure below, in which the wavelengths from left to right are placed in increasing order of magnitude. For most of history, visible light was the only known part of the electromagnetic spectrum. The ancient Greeks recognized that light traveled in straight lines and studied some of its properties, including reflection and refraction. Let's know more about The Electromagnetic Spectrum In Physics.
