I want to know how many people would get this question right....
Calculate the wavelength of radio waves from an AM radio station broadcasting at 1200 kHz.

This only makes sense if the 1.2MHz represents the carrier signal. With AM modulation, this would be the frequency of the transmitted signal (in both DSB and DSB-SC).
lamba = c/f
this signal would supposedly propagate at the speed of light
so, lamba = 299,792,458 [m/s]/1,200,000 [Hz]
lamba = 249.83 m
that should be your wavelength

299,792,458 m/s/1200000 / s = 249.827 m

None. Because AM is done in megahertz
