Kinds of Energy
2.4 and 5.8 GHz or 2400 and 5800 MHz are frequencies used unlicensed by Wifi
The Electromagnetic Spectrum
Here's a good explanation of the difference between Centrifical force verses Centripital force
Since Radio waves travel at the speed of light and Frequency is equal to the number of waves passing a single point in space in 1 second, one can easily see that the length of those waves (which we actually call wavelength) is equal to the speed of light divided by the frequency.
Wavelength × Frequency = Speed of Light
An Antenna is a conductor used to allow radio waves traveling in the air and radio waves traveling in wires in curcuits to communicate with one another. The simplest antenna is called a dipose and is constructed by making 2 conductors, oriented along a line but in opposite directions whose total length (for both of them) is half of the wavelength of whatever frequency you're trying to either receive or transmit through that antenna. We use the greek letter Lamda to represent wavelength. Note that the wire between the middle of the dipole and the output of the transmitter is called a feedline or feeder:
Science, just like Judeism or rednecks has a culture as well as a practice, and they're different. Once can practice one but not the other.
Harmonics are tiny additional transmissions which occur at multiples of the transmitting frequency.
A sine wave is the simplest waveform.
Mixing radio signals makes the original 2 signals plus the sum and difference. But it isn't simple summing; one alters the character of the other in Amplitude Modulation in a non-linear summing function.
