Unformatted text preview: d find the beat period. Find the beat frequency and its uncertainty using the period. Find the predicted beat frequency using the frequencies stamped on the tuning forks. Do the values agree? Comment. Part III: Resonance in a tube PHYSICS 1021 Experiment 3 Part III: Resonance in a tube Apparatus The procedure for this part is shown in the photograph. Hold the microphone at one end of the tube and blow across the other end. PHYSICS 1021 Experiment 3 Part III: Resonance in a tube Predictions QUESTION 5: What do you expect for the shape of a f vs n graph? Explain. QUESTION 6: Write an equation for the slope of a f vs n graph. What do you expect for the intercept? Explain. Refer to plotting and interpreting graphs section in the introduction. You are not supposed to use your data to answer this question. PHYSICS 1021 Experiment 3 Part III: Resonancce in a tube Experimental Method Using the metre stick, measure the length and inner diameter of your tube. Record your results in Table 2. Calculate the end correction of the tube using the equation from the introduction. Record your results in Table 2. Calculate the corrected length of the tube and record your results in Table 2. PHYSICS 1021 Experiment 3 Part III: Resonancce in a tube Experimental Method Launch the LoggerPro program by clicking on the icon below. It should open with two graphs: pressure versus time and amplitude versus frequency (FFT). PHYSICS 1021 Experiment 3 Part III: Resonance in a tube Data Acquisition Click Collect. Blow gently across one end of the tube while holding the microphone at the other end. When you have recorded satisfactory results, click Stop. Your FFT graph will look like the one below. PHYSICS 1021 Experiment 3 Part III: Resonance in a tube Data Acquisition Activate the FFT graph by clicking on it. Click the button and use the cursor to determine the frequencies of the observed harmonics. Record the frequencies of the observed harmonics in Table 3 o...
