What wavelengths are used for radio frequency?
For 90.7 MHz: λ = about 10.84 feet.
Frequency = speed / wavelength . 299,792,458 meters per second / 3.11 meters = 96.396 MHz .
2.4GHz microwave, a band assigned for low power unlicensed users (including microwave cookers) that must tolerate interference from any other user of the band, even if the int…erference makes them inoperative. I think g is also allowed on 4.8GHz microwave.
One convenient working definition of 'radio' is: Electromagnetic radiation with frequency up to 300 GHz / wavelength down to 1 millimeter. 'Radio' is our name for the lowest… frequency / longest wavelength, so there's no lower limit on frequency, or upper limit on wavelength.
Frequency = speed / wavelength = 300,000,000 / 200 = 1500 KHz
Radio Farda is beamed to Iran, from Prague, Czech Republic, in the Persian language. Since it's meant for the Iranian audience, its radio signal is concentrated in that di…rection, and its transmission isn't audible in the US. But ... Radio Farda is available on the internet. Follow the attached link.
wavelength=velocity x frequency wavelength=3x108 x 90.7x103 wavelength=272.1x1011
Divide 300 by the frequency in Megahertz to get the wavelength in metres. the 300 comes from the constant 300,000,000 m/second which is the speed of light (and radio waves).
The frequency is c/10 = 30Mhz.
wavelength would be 3.01507538 Meter in free space.
What is the wavelength in meters of radio waves produced by a radio station with a frequency of 1400 kHz?
Wavelength of radio waves λ is speed of light c divided by frequency f. speed of radio waves c = 299 792 458 m/s and frequency f = 1,400,000 Hz = 1/s Wavelength λ = 299 …792 458 m/s divided by 1,400,000 Hz (cycles/sec)= 214.13747 meters.
Radio waves travel at the speed of light, about 186,282 miles per second in a vacume. The wavelength in meters multiplied by the frequency in megahertz equals about 300.
