Best Answer: Radio frequencies, assuming it's 104.1 FM, are given in megahertz, MHz. 104.1 MHz = 1.041 x 10^8 Hz. For electromagnetic waves, which radio waves are a part of, c = wavelength x frequency 3 x 10^8 = 1.041x10^8 x wavelength wavelength = 2.88 meters Kinda fun to think that something almost 9 feet long is zooming past you over 100million times every second. ^^. 104.1 The Wave.
