cell phones use what type of electromagnetic radiation?
113274
Mobile phones communicate by transmitting radio waves through a network of fixed antennas called base stations. Radiofrequency waves are electromagnetic fields, and unlike ionizing radiation such as X-rays or gamma rays, can neither break chemical bonds nor cause ionization in the human body.

Cell phones, tablets, computers Cell phones and other wireless devices emit radio frequency (RF) energy waves. RF energy is one type of non-ionizing radiation. Government agencies set safety guidelines that limit RF exposure from wireless devices.

EM radiation is classified into types according to the frequency of the wave: these types include, in order of increasing frequency, radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.

Radio waves are at the lowest range of the EM spectrum, with frequencies of up to about 30 billion hertz, or 30 gigahertz (GHz), and wavelengths greater than about 10 millimeters (0.4 inches). Radio is used primarily for communications including voice, data and entertainment media.

4) WiFi Uses Radio Waves Electromagnetic radiation includes everything from gamma rays to visible light to radio waves. Your laptop/tablet/etc. uses a wireless adapter to translate data into a radio signal and transmit that signal using an antenna.

Electromagnetic Radiation. Electromagnetic radiation is energy that is propagated through free space or through a material medium in the form of electromagnetic waves, such as radio waves, visible light, and gamma rays. The term also refers to the emission and transmission of such radiant energy.

Electromagnetic radiation is used for communications and transmission of information. The waves that are used in this way are radio waves, microwaves, infrared radiation and light. The idea of using a signal lamp to communicate was used in the 19th century.

The Electromagnetic Spectrum. The electromagnetic (EM) spectrum is the range of all types of EM radiation. Radiation is energy that travels and spreads out as it goes – the visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of electromagnetic radiation.

Microwaves are a form of "electromagnetic" radiation; that is, they are waves of electrical and magnetic energy moving together through space. Electromagnetic radiation spans a broad spectrum from very long radio waves to very short gamma rays.

Infrared Radiation produces intense heating effect. Radio Waves is used in all cellular devices in order to transmit voice communication from one corner to another.

Mobile phones are, by definition, devices that can detect EMF since their ability to communicate depends on radiofrequency fluctuations in electromagnetic fields. So, apps on a smartphone can, at least in a trivial sense, detect EMF and alter it when they send a signal.

All electromagnetic waves move at the speed of light. Examples of electromagnetic waves include radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma rays. ... Radio waves are used for communications and radar. Microwaves are used to cook your food.

A mobile phone receives microwave signals from a nearby phone mast (or 'transmitter') and sends microwave signals back. These short bursts of microwave radiation can transmit a lot of information in a very short time. You should now know that base stations use radio waves to transmit radio waves to mobile phones.

Microwaves are a type of electromagnetic radiation, as are radio waves, ultraviolet radiation, X-rays and gamma-rays. ... Electromagnetic radiation is transmitted in waves or particles at different wavelengths and frequencies. This broad range of wavelengths is known as the electromagnetic spectrum EM spectrum).

Radio waves have many uses—the category is divided into many subcategories, including microwaves and electromagnetic waves used for AM and FM radio, cellular telephones and TV. The lowest commonly encountered radio frequencies are produced by high-voltage AC power transmission lines at frequencies of 50 or 60 Hz.
