Answers
Given : a pendulum goes from one extreme position A to another extreme position B and then again back to position B in 2 seconds.
To Find : frequency
Solution:
frequency = 1/ Time period
time period of the pendulum is to and fro time from one extreme position to other extreme position
Hence Time period = 2 seconds
=> frequency = 1/2 Hz
frequency is number of cycles per second
a pendulum goes from one extreme position A to another extreme position B and then again back to position B in 2 seconds.
Hence pendulum completes one cycle in 2 seconds
Hence number of cycles in 1 second = 1/2
Frequency of pendulum = 1/2 Hz
