FM-frequency modulation
AM-amplitude modulation
numbers are the killohertz and the megahertz frequencies that a tuner would tune in to the modulation to pick up or receive.or in layman's terms to hear the broadcast.

Normally, in modern day radios they'll measure the frequency of the received carrier wave.
It should be measured in MHz (millions of oscillations per second) for FM and in KHz (thousands of oscillations per second) for AM.

Frequency. On the AM band it's in kiloherz, on the FM band it's megaherz.

AM stands for amplitude modulation and FM for frequency modulation. A wave has certain components. amplitude means distance of a wave from its equlibirium state. thats waht is measured. could it help you? may be not

For AM radio, they are measured in kilohertz, from 550-1600
For FM radio, they are measured in megahertz, they are from 88.1-106.9
