Be sure you understand the relationship between speed (c), frequency (f), and wavelength (X) for electromagnetic waves. The formula is:
Calculate the wavelength of a radio wave whose frequency is 100 KHz (100,000 cycles per second)._
186,000 miles/second 100,000 cycles/second
Speed = Frequency x Wavelength
Wavelength - Speed 300,000 km/second Frequency 100,000 cycles/second
