Question

A pendulum oscilates 30 times in 6 seconds, find its time period and frequency

Answer 1

Time taken for one oscillation is called time period.

∴ Time period = 6 / 30 = 0.2 seconds

Frequency = 1 / Time period = 1 / 0.2 = 5 Hz

Answer 2

Question: A pendulum oscillates 30 times in 6 seconds, find its time period and frequency

Answer:

No. of oscillations = 30

Time Period = 6 seconds

Frequency = No. of oscillations/ Time Period

                  = 30/6 = 5 hertz

Time Period = 1/ Frequency = 1/5= 0.2 seconds

Hence Frequency= 5 hertz and Time Period= 0.2 seconds.
