AM radio signals can usually be heard behind a hill, but FM often cannot. That is, AM signals bend more than FM. Explain. (Radio signals, as we shall see, are carried by electromagnetic waves whose wavelength for AM is typically 200 to 600 m and for FM about 3 m.)
AM radio signals are broadcast at frequencies between 550 kHz (kilohertz) and 1600 kHz and travel at 3 x 10^8 m/s. a) What is the range of wavelengths for those signals? b) FM frequencies range between 88 MHz (megahertz) and 108 MHz and travel at the same speed. What is the wavelength range of the FM frequencies.
