I am getting confused regarding what a 'period' in a pendulum is. In a recent Olympiad/Exam I was given this question..... Can you please give me the method in which it can be done so that I can solve these type of questions with ease if they appear in future..... Thanks A Pendulum oscillates between positions L and R as shown in the figure. It takes 1.2 s to go from L to R and back to the mean position S what is the PERIOD of the pendulum? From my point of view the answer should be 1.6 seconds..... that's what I wrote as an answer but i'm not very sure so I just want to confirm.... Thanks a Lot!
