AM - amplitude modulation
MHz - Mega Hertz. The M means one million (1000000).
FM means frequency modulation, and AM means amplitude modulation.
AM = amplitude modulated. FM = frequency modulated.
RF = Radio Frequency
~ 2.94m
Frequency = speed/wavelength = 300,000,000/3 = 100 MHz.
The frequency is 1000000000 Hz.

To find the frequency of a radio wave, you can use the formula ( f = \frac{c}{\lambda} ), where ( f ) is the frequency, ( c ) is the speed of light (approximately ( 3.00 \times 10^8 ) m/s), and ( \lambda ) is the wavelength. Given a wavelength of 2.5 m, the frequency is calculated as ( f = \frac{3.00 \times 10^8 \text{ m/s}}{2.5 \text{ m}} = 1.2 \times 10^8 \text{ Hz} ) or 120 MHz.
They could mean a lot of things, but in the context of each other they probably stand for Amplitude Modulation and Frequency Modulation (two different methods for sending an audio signal using radio waves) respectively.
The numbers in an FM radio station represent the frequency the station transmits the signal on. The frequency range for FM band radio stations is from 87.5 MHz to 108.0 MHz. These radio frequencies are considered VHF or Very High Frequency. The difference between AM and FM radio is that in AM radio the Amplitude is Modulated, or changed to send the signal, whereas with FM, the Frequency is Modulated or altered to send the signal.
