A pendulum oscillates 40 times in 4 seconds. Find its time period and frequency
Step (1) Given:
No. of oscillations,
Time taken,
Step (2) Finding the time period, T using the formula:
We know that time period,
The time period, of the given pendulum, is
Therefore, the time period of the given pendulum is
Step (3): Finding the frequency, of the pendulum:
We know that
Hence, the frequency of the given pendulum is 10 Hz.
