    PASSAGE-II: If the same motion occurs again and again, it is said to be repetitive motion. Repetitive motion that repeats itself at regular intervals of time is called periodic motion. A pendulum undergoes periodic motion. The time taken by a pendulum to complete its one oscillation is known as its time period. Frequency of a pendulum is defined as the number of oscillations completed in 1 second. If the time taken by the pendulum from C to A is 4 s, then the time taken by it to complete its one oscillation is
