Question

What frequency does a microwave use?

Answer 1

And generally, they operated at a specific frequency: 2.45 GHz. Despite heavy shielding, microwave ovens' powerful emissions could sometimes interfere with neighboring frequencies, so it was decided that they should be given a few megahertz of space in both directions. And so the 2,400-to-2,483.5-Mhz ISM bandwas born.Sep 7, 2010
