    Answer:

    C. All waves have the same speed.

    Explanation:

    Wave equation is given as;

    V = fλ

    where;

    V is the speed of the wave

    f is the frequency of the wave

    λ is the wavelength

    The speed of the wave depends on both wavelength and frequency

    The speed of the electromagnetic waves in a vacuum is 3 x 10⁸ m/s, this also the speed of light which is constant for all electromagnetic waves.

    Therefore, the correct option is “C”

    C. All waves have the same speed.
