If an fm radio station broadcasts at a frequency of 101.3 mhz. what is the wavelength?
a fm radio broadcast communicates at a recurrence of 101.3 mhz. what is the frequency? It shifts with the measurement of the conductor.
The speed factor should be applied in the plan and development of muddled (multi component) recieving wires and their feeders. Feeders change in their impedance and issues emerge in case they are not a decent (preferably awesome) match to the radio wire. This is particularly significant with sending frameworks. A terrible match can be masked or highlighted by the length of the feeder. The possibly inconvenient lengths are an odd number of half rushes (of the favored working recurrence) in the feeder.
101.3 MHz, utilizing the free-space proliferation speed of 300,000,000 meters each second, would be a frequency of 2.962 meters - perhaps. The frequency will change a few if the sign is going through something other a vacuum. In cutting a radio wire for a given recurrence, when the free-space frequency not really settled a speed factor revision is applied to represent the way that eletricity goes at various speeds through various materials - generally more slow than through free space. This implies that albeit the recurrence is as yet differing at a given rate - 101.3 megacycles each second - it is traveling through the conductor all the more leisurely and doesn't go as much distance during one cycle. Consequently the length of a conductor expected to traverse one frequency of a particular recurrence will be less that the free space distance. For instance, the speed factor for a sign going through normal RG-8 persuade link is around 86%. In this manner, 2.962 x 0.86 = 2.54732 meters of RG-8 will be one frequency at the 101.3 MHz signal. Going through RG-213 with a speed component of 66% would give a frequency of: 2.962 x 0.66 = 1.95492 meters. At times these distinctions are exceptionally basic and should be considered -, for example, in radio wire development, some of the time not really, as in the cajole length expected to get a transmission from my transmitter up to the recieving wire on my rooftop. One of the principle factors in the proliferation speed is the dielectric attributes of the wire's protection. For instance, while the speed factor for the protected RG-213 cajole link is around 66%, the speed factor for uninsulated "stepping stool line" transmission line is in the upper 90's.
Thus, responding to your inquiry, the wavelentgth of a 101.3 MHz sign would be a limit of 2.962 meters ! Man, nothing beats accuracy in a reply!!!
Frequency is a distance. Recurrence is in Hz, which is identical to time^-1, explicitly seconds^-1.
Speed = distance/time, or distance * time^-1
Speed of a wave = frequency * recurrence
You can apply your polynomial math abilities to that to acquire a condition for frequency. You have the recurrence and, I trust, the speed of electromagnetic radiation.
