what are the two kinds of fields that make up electromagnetic waves?
14161
At radio and microwave frequencies, electric and magnetic fields are considered together as the two components of an electromagnetic wave. Power density, measured in watts per square metre (W/m2), describes the intensity of these fields.

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.

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.

Examples of electromagnetic waves include radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma rays. Radio waves have the lowest energy and frequency and the longest wavelength. Gamma rays are at the opposite end of the spectrum, with the highest energy and frequency and shortest wavelength.

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. ... The propagation of an electromagnetic wave through a material medium occurs at a net speed which is less than 3.00 x 108 m/s.
891941
Electromagnetic waves are those waves in which electric and magnetic field vectors changes sinusoidally and are perpendicular to each other as well as at right angles to the direction of propagation of wave.

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.

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 can be split into a range of frequencies. This is known as the electromagnetic spectrum. Examples of EM waves are radio waves, microwaves, infrared waves, X-rays, gamma rays, etc.
1320900
Electromagnetic waves are generated by accelerating (or oscillating) charges. The frequency of the wave simply depends on how fast the charge is oscillating.
1150162
There are many types of electromagnetic waves. From lowest energy to highest energy (red to blue) there are radio waves, microwaves, infrared, visible light, ultraviolet, x-rays and gamma rays.
537776
The electromagnetic spectrum is made up of radio waves, microwaves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays. The full spectrum is shown in Figure 2.
684178
Electromagnetic waves are created by the vibration of an electric charge. This vibration movement creates a wave of radiation energy, which has both an electric and a magnetic component. ... Water is originally made up of particles but undulation of particles is observed as wave. Similar is the case of EM radiation.
132816
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.

Transverse electric and magnetic fields produce each other in light, radio waves and other electromagnetic radiation. Here we demonstrate that electromagnetic radiation is a transverse rather than a longitudinal wave.
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.

The electromagnetic spectrum consists of gamma rays, X-rays, ultraviolet radiation, visible light, infrared, and radio radiation.
