This is the velocity of a radio wave. ... The first radio wave has a frequency of one cycle per second (1 Hz). Starting at point A, the wave will move 186,000 miles by the time it completes one cycle and reaches point B.
Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency range from around 20 kHz to around 300 GHz. This is roughly between the upper limit of audio frequencies and the lower … Skatīt vairāk Electric currents that oscillate at radio frequencies (RF currents) have special properties not shared by direct current or lower audio frequency alternating current, such as the 50 or 60 Hz current used in electrical power distribution Skatīt vairāk Communications Radio frequencies are used in communication devices such as transmitters, receivers, computers, televisions, … Skatīt vairāk While RF usually refers to electrical oscillations, mechanical RF systems are not uncommon: see mechanical filter and RF MEMS.
