    The wavelength of a wave varies inversely as its frequency, i. e.

    W ∝ 1/F

    A wave decreases its frequency from 600kHz to 300kHz, so let's calculate the scaling factor of W due to the change in F.

    k = 1 / (300/600) = 2

    To find the new wavelength, multiply the original wavelength by k:

    W = 2*129m

    W = 258m
