how are electromagnetic waves produced what is the source of energy of these waves?
14862
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.

The term also refers to the emission and transmission of such radiant energy. Radiation is all around us. ... Electromagnetic radiation is "energy" that is propagated through the vacuum of space or through a material medium in the form of waves - like radio waves, light waves, X-rays and gamma rays.

In physics, electromagnetic radiation (EM radiation or EMR) refers to the waves (or their quanta, photons) of the electromagnetic field, propagating (radiating) through space, carrying electromagnetic radiant energy. It includes radio waves, microwaves, infrared, (visible) light, ultraviolet, X-rays, and gamma rays.

Electromagnetic waves are generated by moving electrons. ... In turn, the moving electron generates a magnetic field that will also become wavy from the motion of the electron. These combined electrical and magnetic waves reinforce one another. This kind of wave is called an electromagnetic wave and light is such a wave.

Electromagnetic waves consist of both electric and magnetic field waves. These waves oscillate in perpendicular planes with respect to each other, and are in phase. The creation of all electromagnetic waves begins with an oscillating charged particle, which creates oscillating electric and magnetic fields.

Solar radiation is created by nuclear fusion reactions in the sun's core, which causes it to emit a large amount of electromagnetic radiation, mostly in the form of visible light. This radiation is the energy that heats the Earth. The sun's surface emits about 63 million watts of energy per square meter.

Electromagnetic waves. Electromagnetic radiation, is a form of energy emitted by moving charged particles. As it travels through space it behaves like a wave, and has an oscillating electric field component and an oscillating magnetic field.

Electromagnetic waves are used to transmit long/short/FM wavelength radio waves, and TV/telephone/wireless signals or energies. They are also responsible for transmitting energy in the form of microwaves, infrared radiation (IR), visible light (VIS), ultraviolet light (UV), X-rays, and gamma rays.

How are em waves produced by oscillating charges? ... A moving charge produces both electric and magnetic fields, and an oscillating charge produces oscillating magnetic and electric fields. These oscillating electric and magnetic fields with respect to space and time produce electromagnetic waves.
48846
EM waves carry energy and transfer their energy upon interaction with matter. The energy associated with EM radiation is proportional to frequency and inversely proportional to wavelength. Thus, EM waves with shorter wavelengths have more energy.
1044035
Electromagnetic waves are produced by the movement of charged particles. High-frequency electromagnetic waves carry more energy than low-frequency ones. Frequency is determined by the amount of wavelengths that pass in one second.
789184
The EM waves are produced by the accelerated charge. The electron jumping from its outer to inner orbits radiates EM waves. These EM waves are propagated as electric and magnetic fields oscillating in mutually perpendicular directions which is cause of momentum and energy.
125058
Propagation of an Electromagnetic Wave Electromagnetic waves are waves which can travel through the vacuum of outer space. ... Electromagnetic waves are created by the vibration of an electric charge. This vibration creates a wave which has both an electric and a magnetic component.

Moving charges produce both electric and magnetic fields. An oscillating charge produces oscillating magnetic and electric fields. ... the energy associated EM wave is on the expense of energy of source and its frequency is equal to the frequency of oscillating charge. electromagnetic wave are transverse in nature.

Examples of EM radiation include radio waves and microwaves, as well as infrared, ultraviolet, gamma, and x-rays. Some sources of EM radiation include sources in the cosmos (e.g., the sun and stars), radioactive elements, and manufactured devices. EM exhibits a dual wave and particle nature.

Radiation is the transfer of heat energy through space by electromagnetic radiation. Most of the electromagnetic radiation that comes to the earth from the sun is invisible. Only a small portion comes as visible light. Light is made of waves of different frequencies.
