Part 2: Video - Tube Resonance Watch Sound Resonance Tube Calculate Speed of Sound and answer the questions below 3) How does this experiment identify the locations of nodes and antinodes? b) Complete the observation table below while watching the video Experiment Frequency Wavelength Number [Hz) (cm] 1 2 c) When they state the wavelength is 30.0 cm do they mean that the distance between A and B is 39.0 cm? Why or why not? d) Calculate the speed of sound for each experiment and then average your two values. (Hint - change centimeter to meters first) e) The end of the video states the actual speed of sound was 345.5 -. Use the formula below see how far the experimental value (from J) is from the actual value. (9% error is always positive, report any negative answers as positive) % error = # experimental - # actual x 100 # actual f) Discuss two changes that could have been made improve the accuracy of the experiment
