Radio waves are electromagnetic waves. Electromagnetic waves include waves such as X rays, ultraviolet light, visible light, infrared rays and so on, but you probably imagine radio waves to be quite different from these waves. Of the various kinds of electromagnetic waves, radio waves have a longer wave length than infrared rays, and are defined by the Radio Law as 'electromagnetic waves with a frequency of less than 3,000 GHz (3 THz)'

What else can I help you with?
What method of signal transmission uses radio waves to carry signals?
The analog method of signal transmission uses radio waves to carry signals. Digital transmission involves the use of satellites to transmit signals.
What are the different components used in the radio system?
A radio system typically consists of several key components: the transmitter, which converts audio signals into radio waves for transmission; the receiver, which captures these radio waves and converts them back into audio signals; and the antenna, which facilitates the transmission and reception of the radio waves. Additionally, there may be amplifiers to boost signal strength, filters to enhance signal quality, and modulators to encode information onto the carrier wave. Together, these components enable effective communication over radio frequencies.
Do computers use radio waves?
Absolutely. Computing is highly integrated into radio frequency (RF) type communications. Examples of RF integration include Bluetooth, WiFi, and RF peripherals such as the mouse and keyboard.
What are digital formats are descriptions of signals?
Waves
What humans use radio waves?
Radio waves are used to transmit signals from a radio station, and you can receive the signals with a radio, and hear them as sound such as speech or music. The long wavelength of radio waves makes them a suitable medium for transmitting over a large range. it is also use in agriculture...... it is used to diagnose different diseases
Waves used for broadcastig radio signals are called what?
The waves used to broadcast radio signals are called RF waves and these generally lie in VHF and UHF band of electromagnetic spectrum.
Is a radio mechanical energy?
No. Radio waves are a type of electromagnetic waves.
How are radio signals broadcast?
from transmitter through air molecules in the form of waves
How are radio waves utilized in one specific way?
Radio waves are utilized in one specific way by transmitting signals to carry information for communication, such as in radio broadcasting where radio stations use radio waves to broadcast music and news to listeners.
How are radio waves and television signals added to EM radio waves?
by changing the amplitude or frequency of the radio waves.
Cell phone signals are transmitted by?
radio waves radiation
Which waves carries AM and FM signals?
Radio waves
How are radio television signals added to EM radio waves?
by changing the amplitude or frequency of the radio waves.
Are radio waves used to broadcast television programs?
yes
What do baby monitors have to do with Electromagnetic waves?
The monitoring device is a radio transmitter that sends signals to the radio transmitter. Radio waves are a type of Electromagnetic waves.
Was the radio named after radio waves or were radio waves named after the radio?
Radio waves were discovered before the radio was invented.
Which EM waves can carry television signals?
Radio waves. Low frequency.
