👉 That part of the electromagnetic spectrum, between about 3 kHz and 300 MHz, within which radio waves are transmitted.
Alright class, settle down, let’s take a peek, At this puzzling code, so curious and sleek! You've found a definition, clear and bright, About 'rf', a frequency of light – But not the kind you see with your eye, It’s in the airwaves, soaring high! “Radio Frequency,” that’s what it means, Between three kilohertz and three hundred MHz scenes. (Let's break it down a bit, for clarity's plea): kHz (kilohertz) – That’s thousands of Hertz, you see, A tiny measure, for accuracy! MHz (megahertz) - A million Hertz, quite grand, A bigger number, across the land. Think of it like a radio wave's pace, Traveling through space with wonderful grace. It’s used for signals – broadcasts you crave, And communication, both safe and brave! So 'rf' stands for Radio Frequency, my friends, A fascinating part that never ends! Do you have any questions?
