how is an electromagnetic wave produced?
339989
Electromagnetic waves are produced whenever electric charges are accelerated. This makes it possible to produce electromagnetic waves by letting an alternating current flow through a wire, an antenna. The frequency of the waves created in this way equals the frequency of the alternating current.

Light and other electromagnetic waves An electromagnetic wave can be created by accelerating charges; moving charges back and forth will produce oscillating electric and magnetic fields, and these travel at the speed of light.

Electromagnetic waves are produced whenever charged particles are accelerated, and these waves can subsequently interact with any charged particles, they dont interact with neutral particles.

Electromagnetic waves are produced by accelerating charged particle. When the charge moves with acceleration, both the magnetic and electric fields change continuously. This change produces electromagnetic waves. Accelerated charge is the source of energy of these waves.

EM waves are generated by electrically charged particle oscillates (accelerating charges). The electric field associated with the accelerating charge vibrates which generates the vibrating magnetic field. These both vibrating electric and magnetic fields give rise to EM waves.

Electromagnetic waves can be produced by vibrating, electrically charged particles. When the particles vibrate the electric field around it vibrates, too. The vibration of the electric field creates a vibrating magnetic field. The vibrations of the two fields together produce EM waves.

Definition of 'Electromagnetic Waves' Definition: Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields.

Charged particles—such as electrons and protons—create electromagnetic fields when they move, and these fields transport the type of energy we call electromagnetic radiation, or light.

Description: Electromagnetic waves are formed when an electric field comes in contact with a magnetic field. They are hence known as 'electromagnetic' waves. The electric field and magnetic field of an electromagnetic wave are perpendicular (at right angles) to each other. ... EM waves are 'transverse' waves.

Electromagnetic waves are formed when electric field couples with magnetic field. The magnetic and electric field are perpendicular to each other.

Description: Electromagnetic waves are formed when an electric field comes in contact with a magnetic field. ... They are also perpendicular to the direction of the EM wave. EM waves travel with a constant velocity of 3.00 x 108 ms-1 in vacuum. They are deflected neither by the electric field, nor by the magnetic field.

Electromagnetic waves. Electromagnetic (EM) waves are changing electric and magnetic fields, transporting energy and momentum through space. EM waves are solutions of Maxwell's equations, which are the fundamental equations of electrodynamics. EM waves require no medium, they can travel through empty space.

Electromagnetic Waves consist of. vibrating electric and magnetic fields that move through space at the speed of light. Electric Field. a region in which produces electric forces that can push or pull on other charged particles. Magnetic Field.

Electromagnetic waves can be produced by accelerating charges. Moving charges produce both electric and magnetic fields. An oscillating charge produces oscillating magnetic and electric fields. Oscillating charge produce both electric and magnetic field.

Electromagnetic waves are produced when an electric charge is vibrating. 1. Vibrating electric charges are surrounded by vibrating electric and magnetic fields. 2. Vibrating electric and magnetic fields travel outward from the moving charge.

Electromagnetic waves are a form of energy waves that have both an electric and magnetic field. Electromagnetic waves are different from mechanical waves in that they can transmit energy and travel through a vacuum. Electromagnetic waves are classified according to their frequency.

Electromagnetic (EM) radiation is a stream of photons, traveling in waves. ... Low-energy photons (such as radio) behave like waves, while high-energy photons (such as X-rays) behave more like particles. You can read more about how photons work in How Florescent Lamps Work. EM radiation can travel through empty space.
