Emitted by electrically charged particles undergoing acceleration
science.org
- Electromagnetic waves are emitted by electrically charged particles undergoing acceleration, and these waves can subsequently interact with other charged particles, exerting force on them. EM waves carry energy, momentum, and angular momentum away from their source particle and can impart those quantities to matter with which they interact.

Classically, 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.
Electromagnetic 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.

This article explains the different forms of energy, including stored or potential energy and kinetic energy. It also describes mechanical waves and electromagnetic waves as two important ways that energy is transported in the world around us. The article goes on to explain how electricity can be static or changing, forming electromagnetic waves wh...
Energy comes in many forms and can transform from one type to another, including stored or potential energy, kinetic energy, and electromagnetic radiation.
Mechanical waves are caused by a disturbance or vibration in matter while electromagnetic waves do not require a medium to propagate.
Scottish scientist James Clerk Maxwell developed the scientific theory of electromagnetic waves and Heinrich Hertz applied it to radio wave production and reception.
Light is made of photons that carry momentum, have no mass, travel at speed of light with both particle-like and wave-like properties; polarization measures alignment of electromagnetic field.
The terms light, electromagnetic waves, radiation all refer to same physical phenomenon described by frequency/wavelength/energy units for convenient use.
