The formula for the frequency of the pendulum is w2=g/l if you wish to double your period w1, you want to have w2 = 2*w1 The needed length of the pendulum is then l2 = g / w22 = g /(4 * w12) = 0.25 * g / w12 = 0.25 * l1 l2 / l1 = 1/4 You must shorten the length of the pendulum to 1/4 of its former size.
