Electromagnetic (EM) radiation is a form of energy that is all around us and takes many forms, such as radio waves, microwaves, X-rays and gamma rays. Sunlight is also a form of EM energy, but visible light is only a small portion of the EM spectrum, which contains a broad range of electromagnetic wavelengths.

They are used to transmit short or long or FM wavelength radio waves. They are used to transmit TV or telephone or wireless signals and energies. They are responsible for the transmission of energy in the forms of microwaves, visible light, infrared radiation, ultraviolet light, gamma rays and also X-rays.

Communicating in Space Within the electromagnetic spectrum, radio waves are used for spacecraft communications. One of their most beneficial qualities is that radio waves can penetrate the Earth's atmosphere to reach communications equipment on the ground.
212495
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.
714959
Electromagnetic waves cause oscillations in electrical and magnetic fields. They do not need matter to travel through.

Lesson Summary. EM waves originate from the vibration of charged particles, and unlike other waves, they can travel without a medium. The vast range of frequencies for EM waves is described by the electromagnetic spectrum. The spectrum stretches from the lowest frequency radio waves to the highest frequency gamma rays.

Definition: Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields. ... They are also perpendicular to the direction of the EM wave.

Cellular (cell) phones operate with radio frequencies, a form of electromagnetic energy located on the electromagnetic spectrum between FM radio waves and the waves used in microwave ovens, radar, and satellite stations. Cell phones do not emit ionizing radiation, the type that damages DNA.

Radio waves are a type of electromagnetic (EM) radiation with wavelengths in the electromagnetic spectrum longer than infrared light. They have have frequencies from 300 GHz to as low as 3 kHz, and corresponding wavelengths from 1 millimeter to 100 kilometers.

Radio waves are used for communication such as television and radio. Radio waves are transmitted easily through air. They do not cause damage if absorbed by the human body, and they can be reflected and refracted to change their direction. These properties make them ideal for communications.

Definition: Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields. ... They are deflected neither by the electric field, nor by the magnetic field.

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. ... This proved that radio waves were a form of light!
