describe how electromagnetic waves are generated?
474835
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 radiation is one of the many ways that energy travels through space. ... Electromagnetic radiation can be drawn as an oscilating electric field (oscilating in the plane of the page/computer screen), and a perpendicular (in this case, oscillating in and out of the page) magnetic field.

Electromagnetic waves. Electromagnetic waves are transverse waves. Their vibrations or oscillations are changes in electrical and magnetic fields at right angles to the direction of wave travel.

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 transverse waves. Their vibrations, or oscillations , are changes in electrical and magnetic fields at right angles to the direction of wave travel. All electromagnetic waves: transfer energy as radiation from the source of the waves to an absorber.

Like other waves, electromagnetic waves have properties of speed, wavelength, and frequency.... Electromagnetic waves can be described by means of vibrating electrical and magnetic fields which are mutually perpendicular. The nature of these waves is transverse.

Electromagnetic waves are produced by the motion of electrically charged particles. These waves are also called "electromagnetic radiation" because they radiate from the electrically charged particles. They travel through empty space as well as through air and other substances.

The changing magnetic field, in turn, induces an electric field so that a series of electrical and magnetic oscillations combine to produce a formation that propagates as an electromagnetic wave. ... At the same frequency, the magnetic field oscillates perpendicular to the electric field.
1462553
One can imagine electromagnetic waves as series of very regular waves that travel at an enormous speed, the speed of light. The frequency simply describes the number of oscillations or cycles per second, while the term wavelength describes the distance between one wave and the next.

Definition: Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. ... Description: Electromagnetic waves are formed when an electric field comes in contact with a magnetic field. They are hence known as 'electromagnetic' waves.

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.

Characteristics of electromagnetic waves Electromagnetic waves are transverse waves, similar to water waves in the ocean or the waves seen on a guitar string. This is as opposed to the compression waves of sound. As you learned in Wave Motion, all waves have amplitude, wavelength, velocity and frequency.

Types of Electromagnetic Waves. 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.
1460576
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.

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

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.

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.
