Depends on the radio, it can be just about anything.
AM radio frequencies are in KHZ, or thousands of cycles per second. MHZ is 1000 KHZ 648AM on your dial is .648 MHZ
For 90.7 MHz: λ = about 10.84 feet.
Fm radio waves travel at various frequencies between 87.5 MHz and 108.0 MHz
Most work between 300 MHz to 450 MHz.
49 MHz (mhz) is the main radio frequency of the signal that controls a radio-controlled (RC) car. I hope that answers your question. :)
AM radio: 550 KHz to 1650 KHz. (0.55 MHz to 1.65 MHz) FM radio: 88 MHz to 108 MHz. (88,000 KHz to 108,000 KHz)

Single Channel Ground Air Radio Systems (sincgars) can operate in VHF (very high frequency) low band 30.0000 MHz to 89.9999 MHz or VHF high band which is 90.0000 MHz to 224.9999 MHz
Radio signals at frequencies up to roughly 40 to 60 MHz are absorbed or reflected from the ionosphere. At higher frequencies, the signals easily penetrate the ionosphere and continue on into space. This is the reason that AM radio (1 MHz) and "short-wave" broadcasts (4-13 MHz) are often received from great distances, but TV (54 MHz and up) and FM radio (100 MHz) are not.
The frequency can't be 30 Mhz 30 Mhz is a ham radio frequency but to calculate the wavelength, devide 300 by the frequency in Mhz that will give you 10 meters (300/ƒ)
The XM Radio satellites use S-band frequencies from 2,332.50 through 2,345.00 MHz, and Sirius Radio uses adjacent frequencies 2,320.00 through 2,332.50 MHz.
