What experiment(apparatus can be made) can be used to determine the relationship between period and frequency of vibration?

This is rather odd: By definition, frequency and period are reciprocals.

Frequency= 1/period

vibrations/sec= 1/ (seconds/vibration)

The pendulum could be used if you feel a need to measure something.

What's the question?

i cant slove physics questiond

To determine the relationship between the period and frequency of vibration, you can conduct an experiment using a simple pendulum. Here's how you can set up the apparatus:

Materials needed:
1. A long string or thread
2. A weight (such as a small bob or a metal ball)
3. A stopwatch or timer
4. A support stand or clamp
5. A ruler or measuring tape

Procedure:
1. Attach one end of the string to the support stand or clamp, ensuring that it hangs freely without any obstruction.
2. Tie the weight to the other end of the string, creating a pendulum.
3. Measure and record the length of the pendulum from the point of attachment to the center of the weight.
4. Set the pendulum in motion by slightly pulling it to one side and releasing it. Observe its oscillations.
5. Start the stopwatch or timer as the pendulum reaches its highest point while going back and forth, and stop it when the pendulum returns to the same position for the second time (one complete oscillation).
6. Repeat step 5 multiple times and record the time for each oscillation.

Calculations:
1. Calculate the period of the pendulum using the recorded times. The period (T) is the time taken for one oscillation. Divide the total time by the number of oscillations to obtain the average period.
Period (T) = Total Time / Number of Oscillations

2. Calculate the frequency of the pendulum using the period. The frequency (f) is the number of oscillations per unit time, usually measured in hertz (Hz). It is the reciprocal of the period.
Frequency (f) = 1 / Period

3. Plot a graph of the period against the length of the pendulum. Take a range of lengths for the pendulum and repeat steps 3-6 for each length. Note how the period changes with varying lengths.

Analysis:
Analyzing the data and graph will help you determine the relationship between the period and frequency of vibration. In general, you will observe that for a simple pendulum experiment, the period is directly proportional to the square root of the length (T ∝ √L). This relationship indicates that as the length increases, the period also increases. Since frequency is the reciprocal of the period, you can conclude that the frequency is inversely proportional to the square root of the length (f ∝ 1/√L).
