"Meters" is not frequency. It's wavelength.
If you know the wavelength in meters, divide 300 by it, and the result is
the frequency in MHz.
If you know the frequency in MHz, divide 300 by it, and the result is the
wavelength in meters.

Frequency = (speed) divided by (wavelength).
"Speed" is the speed of light in vacuum: 299,792,458 meters per second. When
dealing with radio frequencies and wavelengths, the speed is typically rounded to
300,000,000 meters per second.
(Frequency)Hz = (300,000,000) / (wavelength)meters
(Frequency)KHz = (300,000) / (wavelength)meters
(Wavelength)meters = (300,000) / (frequency)KHz
(Wavelength)meters = (300) / (frequency)MHz
Wavelength = speed/frequency = 300,000,000/100,000,000 = 3 meters
14 megahertz
The commercial AM broadcast band is 0.55 to 1.6 megahertz, with channels spaced 0.01 megahertz. The commercial FM broadcast band is 88.1 to 107.9 megahertz, with channels spaced 0.2 megahertz. Had the questioner proofread his question, we might have known which one he had in mind.
102,000,000 cycles per second
For any wave, frequency x wavelength = speed (of the wave). In this case, convert the kHz to Hz, then divide the speed of light by this frequency. The speed of light should be in meters/second. The answer will be the wavelength in meters.
