Question

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

Answer 1

Answer:

F=1/T

F=20/40=1/2Hz

T=1/F

T=1/1/2=2s

Explanation:

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.
