Question

A simple pendulum makes 20 oscillations in 40 seconds. What is the time period and
frequency of its oscillations.

Answer 1

Answer:

time period=time taken/number of ossilation

time period=40/20

time period=2

frequency=1/time period

frequency=1/2 hertz

Answer 2

Answer:

It is given that,

Number of oscillations made by the simple pendulum, N = 20

Time taken, t = 40 seconds

Let T is the time period of its oscillation. The total number of oscillations per unit time is called frequency of the simple pendulum. It can be calculated as :

The relation between the time period and frequency is given by :

t = 2 seconds

Hence, this is the required solution.
