- The electromagnetic spectrum is typically divided into several categories based on wavelength and frequency: radio waves have the longest wavelengths, while gamma rays have the shortest. Maxwell's equations predict that changes in electric and magnetic fields generate electromagnetic waves, which can travel through a vacuum.

Some common forms of electromagnetic radiation include microwaves, television waves, radio waves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. Each form has different wavelengths and energy levels, resulting in unique properties and applications.
Oct 24, 2024 · electromagnetic radiation, in classical physics, the flow of energy at the universal speed of light through free space or through a material medium in the form of the electric and magnetic fields that make up electromagnetic waves such as radio waves, visible light, and gamma rays.
In physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic (EM) field, which propagate through space and carry momentum and electromagnetic radiant energy. [1] [2] Classically, electromagnetic radiation consists of electromagnetic waves, which are synchronized oscillations of electric and magnetic fields.
Aug 29, 2023 · The electromagnetic spectrum is the continuous spectrum of electromagnetic radiation. It covers an enormous frequency range, from about 1 hertz (Hz) at the extreme low end to over 10 25 Hz at the high end, with no gaps in the frequency range.
Photons. At the quantum level, EM radiation exists as particles. A particle of EM radiation is called a photon. We can think of photons as wave packets —tiny bundles of EM radiation containing specific amounts of energy. Photons are visually represented using the following symbol.
Draw a simplified electromagnetic spectrum, indicating the relative positions, frequencies, and spacing of the different types of radiation bands. List and explain the different methods by which electromagnetic waves are produced across the spectrum.
