The wavelength of a radio signal broadcast at a frequency of 99.0 MHz is?
The wavelength of a 99.0 MHz signal is about 9.94 feet.
What is the frequency of a radio wave 2m in a wavelenght?
Frequency = speed/wavelength = 300,000,000/2 = 150,000,000 = 150 MHz. (The ham-radio band from 144 to 148 MHz is usually called the "two-meter band".)
What type of signal does radio altimeter emits?
A Radio Wave within the RF spectrum range of 4200 - 4400 MHz
What does the number of a FM radio station mean?
The numbers in an FM radio station represent the frequency the station transmits the signal on. The frequency range for FM band radio stations is from 87.5 MHz to 108.0 MHz. These radio frequencies are considered VHF or Very High Frequency. The difference between AM and FM radio is that in AM radio the Amplitude is Modulated, or changed to send the signal, whereas with FM, the Frequency is Modulated or altered to send the signal.
What is the wavelength of a 145 MHz radio signal?
Just divide the speed of light (300 million meters/second) by the frequency, remembering that MHz means "millions of hertz".
The wavelength of a radio signal broadcast at a frequency of 99.0 MHz is?
The wavelength of a 99.0 MHz signal is about 9.94 feet.
What is 49 mhz in a radio controlled car?
49 MHz (mhz) is the main radio frequency of the signal that controls a radio-controlled (RC) car. I hope that answers your question. :)
What is the frequency of a radio wave 2m in a wavelenght?
Frequency = speed/wavelength = 300,000,000/2 = 150,000,000 = 150 MHz. (The ham-radio band from 144 to 148 MHz is usually called the "two-meter band".)
How do you set up the equation for a FM radio has a frequency of 88.9 Mhz determine the wavelength in nanometers?
To determine the wavelenght of a signal, invert it. This would take 88.9 MHz, invert it (1/88.9) giving you 0.01125 microseconds. Now, determine the speed of the signal. Generally, for an FM radio signal, the speed is the speed of light, which is 3 x 108 meters per second. So multiply 0.01125 by 3 x 108, giving 3.75 meters. The question asked for nanometers, so multiply by 1 x 109, giving 3.75 x 109 nanometers for a signal frequency of 88.9 MHz.

How do you communicate with astronauts if radio waves are reflected back to earth?
Radio signals at frequencies up to roughly 40 to 60 MHz are absorbed or reflected from the ionosphere. At higher frequencies, the signals easily penetrate the ionosphere and continue on into space. This is the reason that AM radio (1 MHz) and "short-wave" broadcasts (4-13 MHz) are often received from great distances, but TV (54 MHz and up) and FM radio (100 MHz) are not.
How do you calculate an image frequency?
Let's take an example. Suppose that the intermediate frequency is 10,7 MHz (FM). The local oscillator works on 110,7 MHz. First case: You receive a signal of 100 MHz, the mixer will generate a frequency of 110,7 + 100 = 210,7 MHz, which will be rejected by the band-pass filter. The difference of the two frequencies is 110,7 - 100 = 10,7 MHz (desired one). Second case: You receive a signal of 121,4 MHz. The sum of that frequency and the local oscillator is 232,1 MHz, which will be rejected. The difference is 121,4 - 110,7 = 10,7 MHz. So the image frequency in that case is going to be 121,4 MHz.
How are sound waves converted into radio waves?
Sound waves would not ordinarily be converted INTO radio waves.Sound Waves can be used to modulate the radio waves.The radio frequency of a typical FM station is around 100MHz.The audio is used to vary the FM frequency by the range of audio waves, perhaps 100 Hz up to 12 kHz. So the 100MHz signal varies from 100 MHz ± (100 to 12kHz)
What is the frequency of a radio wave with a wavelength of 3?
Frequency = speed/wavelength = 300,000,000/3 = 100 MHz.
What is frequency of radio wavelength of 3M?
3 Meters ==> 100 MHz 3 Miles ==> 62.137 KHz
