Frequency = 5,775.000.000 Cycles p^r Second (57 75 MHil Wavelength - 2 inches (¿cm)

InFigure 2-2, each cycle of Signal 1 (2.45 GHz) has time to travel 4.8 inches (12 cm). Therefore, Signal 1's wavelength is 4.8 inches (12 cm). Signal 2 is changing more rapidly; each cycle of Signal 2 has time to travel only 2 inches (5 cm). Therefore, the wavelength of Signal 2 is only 2 inches (5 cm). There is a corresponding physical wavelength for every wireless frequency. The lower the frequency, the longer the wavelength; the higher the frequency, the shorter the wavelength.
