What type of waves transmit cellular telephone messages?

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.

What radiation is used to transmit cellular phone calls?

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.

What type of radiation is used for communication?

radio waves
Search form 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.

What type of waves are used on a TV remote control?

Infrared waves, or infrared light, are part of the electromagnetic spectrum. People encounter Infrared waves every day; the human eye cannot see it, but humans can detect it as heat. A remote control uses light waves just beyond the visible spectrum of light—infrared light waves—to change channels on your TV.

What is radiation and how it is used for communication?

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 to change their direction. These properties make them ideal for communications.

What kind of radiation does a mobile phone emit?

There is much overlap between many of these types of electromagnetic radiation. The radiation emitted by mobile phones falls somewhere in between microwaves and radio waves. These are often called radio frequencies (RF). So What Radiation Do Mobile Phones Produce?

What kind of radio waves does a cell phone use?

Cellular phone networks utilize multiple bands of EM spectrum, one of which is called UHF, or ultra-high frequency, sometimes known as microwave The frequency range for microwave radiation is between 300 megahertz and 300 gigahertz.

How does a cell phone talk to a radio?

Radio frequencies are powerful over long ranges and provide an efficient means for radio towers to connect to our phone antennae. Your phone ‘talks’ via its antennae to these radio towers, and this connects it to the network. In addition to that, the electronic components of phones also produce microwaves and radio waves.

Is it true that radiation from cell phones can cause cancer?

We don’t know for sure if RF radiation from cell phones can cause health problems years later. The International Agency for Research on Cancer (IARC) has classified RF radiation as a “possible human carcinogen.” (A carcinogen is an agent that causes cancer.)
