Question

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

Answer 1

Answer :-

• 2 Hz
• 0.5 s

Explanation :-

Given :

• No.of oscillations = 40
• Time taken = 20

To find :

• Time period.
• Frequency.

Solution:

Frequency:

• No.of oscillations/Time taken

=> 40/20

=> 4/2

=> 2 Hz

Time period:

• 1/Frequency

=> 1/2

=> 0.5 s
