    Answer:

    11m

    Explanation:

    Wavelength of a wave is the distance between successive crests and trough of a wave. It is represented mathematically as the ratio of the speed of the wave to its frequency. It can be expressed as;

    Wavelength ¶ = wave speed (v) /frequency (f)

    Given the speed of light c = 2.9979 10^8 m/s.

    frequency of the radio wave = 27.075 MHz = 27.075×10^6Hz

    Wavelength = 2.9979 10^8/27.075×10^6

    Wavelength = 0.11×10^2

    Wavelength = 11m

    Therefore, the wavelength of the electromagnetic wave being used is 11m
