AM radio signals are broadcast at frequencies between 540 kHz and 1585 kHz (kilohertz) and travel 3.0 X 10^8 m/s.
a. What is the range of the wavelengths for the signals? (from shortest to longest).
b. FM frequencies range between 88MHz and 108 MHz (megahertz) and travel at the same speed. What is the range of FM wavelengths?
Wavelength LAMBDA= Light speed/Frequency =
3x10^8/540x100 = ....
