$lambda ~~ 166.7" m"$

Convert the frequency from $"kHz"$ to $"Hz"$ :

$1800" kHz" to 1.8xx10^6" Hz"$

Let $f = 1.8xx10^6" Hz"$

Let $C= 3.0 xx 10^8" m/s"$ (the speed of the radio signal)

Let $lambda =$ the unknown wavelength (in meters):

$lambda = C/f$

$lambda = (3.0 xx 10^8" m/s")/(1.8xx10^6" Hz")$

$lambda ~~ 166.7" m"$
