Estimate the wavelength for 1.9 ghz cell phone reception. what is the wavelength of the waves on which the radio station wham 1180 operates?

Wavelength = (speed) / (frequency)

Speed of radio in air = approximately 3 x 10⁸ m/s

Cell phone:  Frequency = 1.9 GHz = 1.9 x 10⁹ Hz

Wavelength = (3 x 10⁸ m/s) / (1.9 x 10⁹ /sec) = 15.79 cm (6.2 inches)

WHAM:  Frequency = 1180 KHz = 1.18 x 10⁶ Hz

Wavelength = (3 x 10⁸ m/s) / (1.18 x 10⁶ /sec) = 254.2 meters (0.16 mile)

I KNOW there must be somebody around here from Rochester NY.
My roomie and I used to wake up to WHAM when we were in college there.
