    Answer:

    λ = 2.94 m (in meters)

    λ = 2.94 x 10⁹ nm (in nanometers)

    λ = 2.94 x 10¹⁰ A (in angstrom)

    Explanation:

    The wavelength of the radio station can be given as follows:

    \lambda = \frac{c}{f}\\

    where,

    λ = wavelength = ?

    f = frequency = 102 MHz = 1.02 x 10⁸ Hz

    c = speed of light = 3 x 10⁸ m/s

    Therefore,

    \lambda = \frac{3\ x\ 10^8\ m/s}{1.02\ x\ 10^8\ Hz}

    λ = 2.94 m (in meters)

    λ = (2.94 m)(10⁹nm / 1 m)

    λ = 2.94 x 10⁹ nm (in nanometers)

    λ = (2.94 m)(10¹⁰ A / 1 m)

    λ = 2.94 x 10¹⁰ A (in angstrom)
