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. An electromagnetic wave transports its energy through a vacuum at a speed of 3.00 x 108 m/s (a speed value commonly represented by the symbol c).

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.

Like all other electromagnetic waves, radio waves travel at the speed of light in vacuum. They are generated by electric charges undergoing acceleration, such as time varying electric currents. ... Radio waves are generated artificially by transmitters and received by radio receivers, using antennas.

(b) How do you convince yourself that electromagnetic waves carry energy and momentum ? (a) The electromagnetic waves are produced by the accelerated charge. The electric and magnetic fields produced by the accelerated charge change with time. Hence, it radiates electromagnetic waves.

For example water waves propagate in water, whereas EM waves can exist in a vacuum. EM waves are made up of oscillating electromagnetic and magnetic fields, whereas mechanical waves are just fluctuations in a medium. EM waves travel at the speed of light 3x10^8 m/s, whereas mechanical waves travel slower.

Electromagnetic Wave: Electromagnetic waves are a self-propagating transverse wave of oscillating electric and magnetic fields. ... This means that an electric field that oscillates as a function of time will produce a magnetic field, and a magnetic field that changes as a function of time will produce an electric field.

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.

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 waves that consist of vibrating electric and magnetic fields. They transfer energy through matter or across space. The transfer of energy by electromagnetic waves is called electromagnetic radiation. ... When it travels through space, it doesn't lose energy to a medium as a mechanical wave does.

Wireless networks operate using radio frequency (RF) technology, a frequency within the electromagnetic spectrum associated with radio wave propagation. When an RF current is supplied to an antenna, an electromagnetic field is created that then is able to propagate through space.

Electromagnetic waves are produced whenever charged particles are accelerated, and these waves can subsequently interact with any charged particles." First, a magnetic field does no work. ... Magnetic fields generate electric fields inside an object and that's how work is produce.

Radio waves are created by the acceleration of electrons in a radio antenna, and light waves are created by the oscillations of the electrons within atoms. The electromagnetic wave has two components: the electric radiation field and the magnetic radiation field.

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.

Electromagnetic waves transport energy and momentum across space. The energy and momentum transported by an electromagnetic wave are not continuously distributed over the wave front. Energy and momentum are transported by photons in discrete packages.

The electromagnetic spectrum is comprised of all frequencies of electromagnetic radiation that propagate energy and travel through space in the form of waves. Longer wavelengths with lower frequencies make up the radio spectrum. Shorter wavelengths with higher frequencies make up the optical spectrum.

Explain how an electromagnetic wave can travel through space that contains no matter. An electromagnetic wave is made of vibrating electric and magnetic fields that continually induce each other; matter is not needed for this to occur. ... No; No; they have to move to produce a wave.
