23.2: Electromagnetic Waves and their Properties
WEBElectromagnetic Wave: Electromagnetic waves are a self-propagating transverse wave of oscillating electric and magnetic fields. The direction of the electric field is indicated in blue, the magnetic field in red, and the wave propagates in the positive x-direction.
Electromagnetic radiation - Wikipedia
WEBClassically, electromagnetic radiation consists of electromagnetic waves, which are synchronized oscillations of electric and magnetic fields. In a vacuum, electromagnetic waves travel at the speed of light, commonly denoted c. There, depending on the frequency of oscillation, different wavelengths of electromagnetic spectrum are produced.

16.7: Electromagnetic Waves (Summary) - Physics LibreTexts
WEBElectromagnetic waves carry momentum and exert radiation pressure. The radiation pressure of an electromagnetic wave is directly proportional to its energy density. The pressure is equal to twice the electromagnetic energy intensity if the wave is reflected and equal to the incident energy intensity if the wave is absorbed.

Electromagnetic Waves – The Physics Hypertextbook
WEBThe poynting vector is important because it aligns the three vectors of an electromagnetic wave: the electric field, the magnetic field, and the direction of propagation. These three vectors are mutually perpendicular; that is, each is perpendicular to the other two.
Chapter 2.1: Waves and Electromagnetic Radiation
WEBJul 30, 2021 · A basic knowledge of the electronic structure of atoms requires an understanding of the properties of waves and electromagnetic radiation. A wave is a periodic oscillation by which energy is transmitted through space. All waves are periodic, repeating regularly in both space and time.
