Electromagnetic it can be air, solid or vacuum

Electromagnetic waves or EM waves are waves created due to vibrations between electric fields and magnetic fields.

In other words, the EM wave consists of magnetic and electric fields swinging. Electromagnetic waves are used to transfer either short, long or FM radio waves, and the TV, phone, wireless or energy signals. They are also in charge for transmitting energy in the form of microwaves, infrared radiation, visible light, ultraviolet light, X-ray, and gamma rays.  DESCRIPTIONAn electromagnetic wave is formed when the electric field meets the magnetic field.

They are known as electromagnetic waves. Electrical fields and magnetic fields of electromagnetic waves perpendicular to the exact angle of each other. They are also perpendicular to the EM wave direction. Electric charge vibrations create electromagnetic waves.

This vibration creates a wave that has both electric and magnetic components. Electromagnetic waves transport energy through vacuum at speeds of 3.00 x 108 m / s.

The spread of electromagnetic waves through material media occurs at net speeds less than 3.00 x 108 m / s. They are not defended by electric fields, or by magnetic fields. However, they may show distortion or divergence. Electromagnetic waves can move through anything, it can be air, solid or vacuum material.

It does not require the medium to propagate or travel from one place to another. Mechanical waves such as sound waves or water waves, require a medium to move. The EM wave is a ‘transverse’ wave. This means they are measured by the amplitude or altitude and the wavelength which is the distance between the highest or lowest point two successive waves. The highest point of the wave is known as ‘peak’, while the lowest point is known as ‘trough’.

Electromagnetic waves can be divided into various frequencies. This is known as the electromagnetic spectrum. Examples of EM waves are radio waves, microwaves, infrared waves, X-rays, gamma rays, and so forth.
