Both of these are part of the electromagnetic spectrum. The main difference between the two is the wavelength and frequency. (Frequency multiplied by Wavelength always equals the Speed of Light, the constant abbreviated as "c". This is approximately equal to 186,000 miles per second or 300,000 km per second. If you know the wavelength and you want to find the frequency, divide "c" by the wavelength. )
The wavelength of electromagnetic radiation is a measure of the frequency; multiply the frequency times the wavelength, and the answer is ALWAYS the "Speed of Light", which we abbreviate as "c". All of these are different "bands" of electromagnetic energy. Radio is the longest wavelength and lowest frequency. "Low Frequency" is the lowest, followed by "high frequency", "very high frequency" or VHF, "ultra-high frequency" or UHF. Beyond that are microwaves, and then heat, then "infrared", and then visible light. Higher frequency (and shorter wavelengths) than light are "ultra-violet", then X-rays, and then "gamma rays".
In Canada, there are two radio stations broadcasting on 1320 AM. The Vancouver area picks up radio station CHMB at that frequency, while the Oakville, Ontario area receives radio station CJMR.
The length of a wave is denoted by its wavelength, which is found by dividing the speed of light, or c, (3 x 108 m/s) by the frequency (88 x 106 Hz). The answer is 3.4 meters.
The relation to be used: Speed of light c = frequency * wavelengthWavelength = c / frequency,where speed of light c = 2.998 * 108 m/sThe wavelength is therefore 0.34 metres or 34cm or 340mm
Fm radio waves travel at various frequencies between 87.5 MHz and 108.0 MHz
Wavelength = (speed of light) / (frequency) = (300,000,000 m/s) / (830,000) = 361.4 meters (rounded)
Frequency = speed/wavelength = 300,000,000/3 = 100 MHz.
Frequency = speed/wavelength = 300,000,000/150 = 2 MHz
Frequency = speed/wavelength = 300,000,000/3 = 100 MHz.
Speed, wavelength and frequency.
One convenient working definition of 'radio' is: Electromagnetic radiation withfrequency up to 300 GHz / wavelength down to 1 millimeter.'Radio' is our name for the lowest frequency / longest wavelength, so there'sno lower limit on frequency, or upper limit on wavelength.
The energy of EM radiation depends on its frequency, and the lowest frequency corresponds to the lowest energy. Radio waves are at the low end of the energy and frequency spectrum.
Radio waves
Radio waves are the lowest frequency (and therefore longest wavelength) waves in the electromagnetic spectrum.
The wavelength is greater than 300E6/300E9 = 1 mm and the frequency is less than about 300 Gigacycles.
The frequency of a radio wave in Hertz (cycles per second) multiplied by the wavelength of the radio signal (in meters) is always equal to the speed of light, which is equal to The speed of light has the symbol "c". So Frequency/c = wavelength, and wavelength/c = frequency. == ==
