Response Details:
wavelenght = λ = v/f
so you need the velocity of the radio wave to solve this problem, i am not sure if this is given or you may have to look it up but all you need to do then is divide the velocity by frequency
 
hope this helps some!

Response Details:
as we know that

speed of light c = λf

so

wavelength λ= c/f

=3*108/2*106

= 150 m
