Electromagnetic Waves

Electromagnetic Waves are currents that are formed when an electric field and a magnetic field vibrate together. Electromagnetic Waves  are made up of alternating magnetic and electric fields. When an electric field collides with a magnetic field, electromagnetic waves are created. As a result, they are referred to as "electromagnetic" waves. The electromagnetic wave's electric and magnetic fields are parallel to one other. They are also parallel to the Electromagnetic wave's path.

In vacuum, Electromagnetic waves have a constant velocity. They are not deflected by either the electric or magnetic fields. They are, nonetheless, capable of displaying distortion and refraction. An electromagnetic wave can pass through any medium, including air, solid matter, and vacuum. It does not require a medium to expand or move from one location to another. Mechanical waves, on the other hand, require a medium to propagate such as sound or liquid waves. Electromagnetic  Waves are referred to as 'transverse' waves. This means that their amplitude and wavelength are used to determine their size.

The highest point of a wave is called the crest, while the lowest point is called the trough. The frequency of electromagnetic waves can be divided into a number of categories. The electromagnetic spectrum is what we call this. Radio waves, microwaves, infrared waves, X-rays, and gamma rays are all examples of electromagnetic waves.

The whole dispersion of electromagnetic waves according to frequency or wavelength is referred to as the electromagnetic spectrum. In a vacuum, all electromagnetic waves close to the speed of light, but at a wide range of frequencies, wavelengths, and particle energies. The electromagnetic spectrum encompasses all electromagnetic waves and is divided into numerous subranges such as visible light and ultraviolet radiation.

The various parts have various terms due to changes in the behavior of the respective waves in terms of emissions, reception, and absorption, as well as their diverse practical applications. The ranges tend to overlap since there are no definite acceptable boundaries between any of these continuous components.

All radio waves such as commercial radio and television, microwaves, radar, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays are all part of the electromagnetic spectrum, which extends from the lowest to highest frequency as well as longest to shortest wavelength. For spectroscopic, nearly all frequencies and wavelengths of electromagnetic radiation can be exploited.
