What else can I help you with?
AM wave frequencies are?
AM stands for Amplitude Modulation. Whatever radio frequency you use, a single frequency would just produce silence at the receiver. You need to superimpose sound frequencies onto the carrier wave. Amplitude modulation does this by varying the Amplitude (strength, power) of the radio carrier wave in time with audio frequency. AM is therefore the kind of 'coding' used and has nothing to do with frequency. By convention, amplitude modulation is mostly used in the medium and long, radio waves. From 150 to 1600 Khz. AM is also used for air band communications at 121Mhz, whereas FM is used at marine frequencies of 156Mhz.
What is are unlicensed radio frequencies?
Those which you can use for free, for instance a tv remote control uses such frequencies.
A wave travels through space on its way to a communications satellite. What kind of wave is it most likely to be?
The wave making the trip to the communications satellite will be a radio wave, which is an electromagnetic wave. Electromagnetic waves can move through the vacuum of space because they do not need a medium in which to travel. We usually use the microwave band of frequencies to communicate with satellites.
What frequencies do FRS radios use?
The frequencies that FRS radios use is channels 8 to 14 and 462 to 467. FRS radios are Family Radio Service radios and can be bought from Radio Shack and Amazon.
What is the freqs for satellite radio?
The XM Radio satellites use S-band frequencies from 2,332.50 through 2,345.00 MHz, and Sirius Radio uses adjacent frequencies 2,320.00 through 2,332.50 MHz.
What radio frequencies do international air flights use?
110 to 130 MHz.
What is the main use of frequency modulation?
Frequency modulation is used to broadcast radio waves to receivers. The most common use of it is in FM radio, which contains a range of radio frequencies.
What freqencies does a AM radio use?
AM radios can use frequencies in the range 535 kHz to 1605 kHz. Frequencies are assigned at 10 kHz intervals, from 540 kHz to 1600 kHz.
What is a radio wave?
Radio waves are electromagnetic waves. The radio waves have the longest wavelengths in the electromagnetic spectrum. A radio wave has a much longer wavelength than does visible light. We use radio waves extensively for communications.
What is the rate of oscillation for a radio frequency?
The rate of oscillation for a radio frequency is typically measured in hertz (Hz). For example, AM radio frequencies oscillate at around 535-1605 kHz (kHz = kilohertz) while FM radio frequencies oscillate at around 88-108 MHz (MHz = megahertz).
Do people use the Morse code today?
Yes, but almost completely as a hobby (ham radio).A2. For communicating with submerged submarines, use is made of Very Low Frequencies,
What type of data does Bluetooth use?
Digital data sent over UHF radio frequencies.
