    For an RC circuit, impedance Z is given by:

    Z = 1/wC, where w is omega and C is capacitance

    Now w = 2πf, where f is frequency

    So Z = 1/2πfC

    This means that impedance Z is inversely proportional to frequency f.

    So Z1/Z2 = f2/f1

    Since f1 = f and f2 = 2f:

    f2/f1 = 2f/f = 2

    So Z1/Z2 = f2/f1 = 2
