Question

8. How do you measure the time period of a given
pendulum ? Why do you note the time for more
than one oscillation ?and how can you find time period ​

Answer 1

Answer:

Time period is the time taken by the body to complete one oscillation and it is noted more than once to get accurate reading from averaging of all the observed values

hope it is helpful to you

Answer 2

Answer:

Calculate the time of one oscillation or the period (T) by dividing the total time by the number of oscillations you counted. Use your calculated (T) along with the exact length of the pendulum (L) in the above formula to find "g." This is your measured value for "g." Repeat the above procedure for 3 more cases.

Time period is the time taken by the body to complete one oscillation and it is noted more than once to get accurate reading from averaging of all the observed values

The formula for time is: T (period) = 1 / f (frequency). λ = c / f = wave speed c (m/s) / frequency f (Hz). The unit hertz (Hz) was once called cps = cycles per second.
