Question

What is the length of simple pendulum which ticks the seconds? ​

Answer 1

EXPLANATION

What you want is a pendulum with a frequency of 1/2 Hz. It swings left for 1 second,

then right for 1 second, ticks once in each direction, and completes its cycle in exactly

2 seconds.

The length of such a pendulum technically depends on the acceleration due to gravity

in the place where it's swinging. In fact, pendulum arrangements are used to measure

the local value of gravity.

A good representative value for the length of the "seconds pendulum" is 0.994 meter.
