how electromagnetic waves are generated and propagated in space?
7049
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.

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 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.

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 waves are waves which can travel through the vacuum of outer space. ... 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).

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 Radiation. ... 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 electromagnetic spectrum is a continuum of all electromagnetic waves arranged according to frequency and wavelength. The sun, earth, and other bodies radiate electromagnetic energy of varying wavelengths. Electromagnetic energy passes through space at the speed of light in the form of sinusoidal waves.

Propagation of an Electromagnetic Wave Electromagnetic waves are waves which can travel through the vacuum of outer space. ... Sound waves are examples of mechanical waves while light waves are examples of electromagnetic waves. Electromagnetic waves are created by the vibration of an electric charge.

An electromagnetic wave begins when an electrically charged particle vibrates. This causes a vibrating electric field, which in turn creates a vibrating magnetic field. The two vibrating fields together form an electromagnetic wave.

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.

Propagation of an Electromagnetic Wave Electromagnetic waves are waves which can travel through the vacuum of outer space. ... When an electromagnetic wave impinges upon the atoms of a material, the energy of that wave is absorbed. The absorption of energy causes the electrons within the atoms to undergo vibrations.

Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.

Electromagnetic waves are waves which can travel through the vacuum of outer space. Mechanical waves, unlike electromagnetic waves, require the presence of a material medium in order to transport their energy from one location to another.
