How much time does the bob of a seconds’ pendulum take to move from one extreme of its oscillation to the other extreme?

As we know that, the time period of a seconds’ pendulum is 2s.

So, time taken for a seconds’ pendulum to move from one extreme to other is equal to the half of time period.

T_half = T/2

⇒ T_half = 2/2 = 1 s

Hence, time taken for a seconds’ pendulum to move from one extreme to other extreme = 1s
