To solve, let's consider the period of the pendulum. The formula of period is:

`T= 2pisqrt(L/g)`

where T is the period, L is the length of pendulum and g is the acceleration due to gravity.

Take note that the frequency is the reciprocal of period.


Plugging in the formula of T, it becomes:


`f=1/(2pi) sqrt(g/L)`

Based on this, the frequency is inversely proportional to the length.
