    Answer:

    3.41m

    Explanation:

    The following were obtained from the question:

    f (frequency) = 8.81×10^7Hz

    V (velocity of electromagnetic wave) = 3×10^8 m/s

    λ (wavelength) =?

    Velocity, frequency and wavelength of a wave are related with the equation below:

    V = λf

    λ = V/f

    λ = 3×10^8 /8.81×10^7

    λ = 3.41m

    Therefore, the wavelength of the radio wave is 3.41m
