From around 100kHz to around 500MHz. Below that, antennae need to be rather long to be efficient, above that the transmission range gets a bit short. But people have used much lower, and much higher frequencies, 40Hz - 20Gz and higher. The very high frequencies are often called microwave links.
What else can I help you with?
How do you replace a radio in a 1996 Dodge Intrepid?
Remove the plastics with a flat head screwdriver (be careful not to break the plastic clamps) surround the face fo the radio. Unscrew (should be four) screws remove radio and make sure to disconnect wiring harness and ground wire. Enjoy.

No not at all
If Two waves are traveling in the same medium with a speed of 340ms What is the difference in frequency of the waves if the one has a wavelength fo 5m and the other has a wavelength of 0.2m?
For a wavelengt lambda in air with the speed of sound of c = 340 meters per second the frequency f: f = c / lambda. A wavelength of 5 meters equals a frequency of 68 Hz. A wavelength of 0.2 meters equals a frequency of 1700 Hz. There is a useful calculator for converting wavelength to frequency and vice versa. Scroll down to related links and look at "Acoustic waves or sound waves in air".

What frequency would she hear as the siren moves away from her at the speed of Vs equals 49ms?
f = C fo / (C + vs)(Assuming speed of sound, c = 330 m/s),f = 330 fo / (330 +49 ) frequency that she would hear isf = 0.87 f0
FITT fo the FITT principle stands for full integrated training technique?
False. Stands for Frequency, Intensity, Time, and Type
Which uses single frequency digital signals?
I was told it is x(n) = 10*sin(2*pi*fo*Ts(n-1)) + 8*sin(2*pi*2*fo*Ts(n-1)) + 6*sin(2*pi*3*fo*Ts(n-1))
State the the frequency at antiresonance?
For a series a.c. circuit, resonance occurs when the inductive reactance is equal to the capacitive reactance. You can work out the frequency at which this occurs by inserting the variables into the following equation:XL = XC
Why fo scientists say the earth has to little AND to much ozone?
It is because ozone acts as a blanket to earth. It protects us from high frequency UV rays.
What is threshold frequency?
Threshold frequency is the minimum frequency of light required to eject electrons from a metal surface in the photoelectric effect. Below this frequency, no electrons are emitted regardless of intensity. It is a characteristic property of each metal and is used to determine the work function of the metal.

The radio cahnnel fo Kiis FM is 102.7. Also check out 103.7, 104.9, And on the AM side, 830, and 640.
How does a tank circuit filter out frequencies?
Without writing a book, the tank circuit (tank) is what is called a tuned circuit. The basic tank circuit has an inductive component (a coil) and a capacitive component (a cap). There are a couple of concepts that you need to get a handle on. A tank has a given "resonance" based on the net inductance and capacitance. It has one frequency that it really likes to run at. That's the resonant frequency (fo). The tank is tuned for that fo. A signal at that frequency that is put into the stage that has a tank filter will cause the tank to "ring" electronically. The signal oscillates in the tank, and, because it's the fo for that tank, some maximum amplitude (gain) will be attained. The signal is then coupled out. Other signals of a slightly different frequency will cause the tank to ring, but not as much. As a signal is put into the stage that is a bit higher or lower than the fo, it causes less oscillation, and it emerges at a lower amplitude. Notice that this applies to signals that are a bit above or a bit lower than the fo. The farther from the fo that a given signal is, the less oscillation it produces in the tank, and the less gain it will be given in that stage. Again (and it's worth repeating), signals both above and below the fo a given distance produce the same oscillation in the tank. That means the tank responds to both sides of the spectrum above and below the fo. Lastly, the tank can be "sharply tuned" or not. In a sharply tuned tank, the signals that are farther from fo cause little tank action, and those right around fo really get a lot of gain. In something less sharpely tuned, there is still a good bit of gain for frequencies higher or lower than the fo. We spoke of the tuning of the tank for a particular fo. Now we have to tune the tank for what is called quality (Q). This speaks to how "tightly" the tank is tuned. And we have to make a trade. If we want a lot gain at fo and little else, high Q is the way to go. There will be a ton of gain at fo, and the gain for frequencies above and below will drop like a rock. In a less tightly tuned tank, there will be better gain for the frequencies around fo, but not as great a gain for the fo itself as there would be in a high Q tank. That's the trade. Narrow tuning yields greater gain for the fo and lower "bandpass" while broader tuning will pass "more frequencies" (have a higher band pass) but with lower gain at and right around the fo than a high Q tank.
