Question

(iii) A simple pendulum makes 5 oscillations in 10 seconds. What is the time period and
frequency of its oscillation.​

Answer 1

Answer:

Time period = 2 seconds

Frequency = 0.5 s⁻¹

Explanation:

Time period (T) is the time taken to complete one oscillation.

The pendulum makes 5 oscillations in 10 seconds. We have to find out how much time it takes to complete one oscillation.

5 osc → 10 sec

1 osc → $\frac{10}{5}$ = 2 sec

It takes 2 seconds to complete one oscillation.

Frequency is the number of oscillations occuring in one second.

Now, to calculate the frequency of its oscillation, we find the number of oscillation in 1 second.

1 sec → $\frac{5}{10}$ = 0.5 s⁻¹ or 0.5 Hz

Conclusion:

The time period is 2 seconds and the frequency is 0.5 s⁻¹.
