#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"#
