    frequency = 0.47*10⁴ Hz

    Explanation:

    Given dа ta:

    Wavelength of wave = 6.4 * 10⁴ m

    Frequency of wave = ?

    Solution:

    Formula:

    Speed of wave = wavelength * frequency

    Speed of wave = 3 * 10⁸ m/s

    Now we will put the values in formula.

    3 * 10⁸ m/s = 6.4 * 10⁴ m * frequency

    frequency = 3 * 10⁸ m/s / 6.4 * 10⁴ m

    frequency = 0.47*10⁴ / s

    s⁻¹ = Hz

    frequency = 0.47*10⁴ Hz

    Thus the wave with wavelength of 6.4 * 10⁴ m have 0.47*10⁴ Hz frequency.
