The Capacitance(C) is inversely proportional to f(frequency). So to increase capacitance voltage , f must be decreased.

V = iXc.
Xc = 1/(2*pi*f*c).
So, voltage is inversely proportional to the frequency.
If increase the voltage then frequency should be decreases.
Xc = 1/(2*pi*f*c).
So, voltage is inversely proportional to the frequency.
If increase the voltage then frequency should be decreases.

F=1/T.
If frequency is decreasing then time period is increasing.
If frequency is decreasing then time period is increasing.
