1 Activity P45: Resonant Modes and the Speed of Sound (Voltage Sensor, Power Output) Concept DataStudio ScienceWorkshop (Mac) ScienceWorkshop (Win) Waves P45 Speed of Sound 2.DS P36 Speed of Sound P36_MACH.SWS Equipment Needed Qty Equipment Needed Qty Voltage Sensor (CI-6503) 1 Resonance Tube (WA-9612) 1 Patch Cords (SE-9750) 2 What Do You Think? The speed of sound can be determined by various methods. How can you calculate the speed of sound in a column of air inside a tube? Take time to answer the What Do You Think? question(s) in the Lab Report section. Background For a given frequency of sound in a resonance tube, there are a variety of tube lengths at which a standing wave will be formed. Likewise, for any given tube length, there are a variety of resonant frequencies frequencies at which standing waves will be formed in the tube. In general, if the sound frequency is many times higher than the lowest resonant frequency (the fundamental frequency) for the tube, there will be several nodes and antinodes in the standing wave. For an open tube, the distance between successive antinodes in a standing wave is onehalf wavelength. The speed of sound is the product of the wavelength and the frequency, or v = λ f where v is the speed of sound, λ is the wavelength, and f is the frequency. SAFETY REMINDER Follow all safety instructions. For You To Do Use the Output feature of the interface to drive a speaker to vibrate the air inside a Resonance Tube at a fixed frequency (1000 Hz). Use DataStudio or ScienceWorkshop to control the speaker s output frequency with the Signal Generator. Use a microphone mounted in the Resonance Tube to measure the amplitude of sound. Use the Voltage Sensor to measure the signal from the microphone. Use a piston inside the tube is used to adjust the length of the column of air inside the tube. Use the software to display the output signal of the speaker, and the input signal from the microphone. Change the position of the piston to determine the distances between successive antinodes in the standing sound waves that occur inside the tube. Use the distance to determine the wavelength of the sound and then calculate the speed of sound. P PASCO scientific p. 75

2 Physics Labs with Computers, Vol. 2 Student Workbook P45: Resonant Modes and Speed of Sound A PART I: Computer Setup 1. Connect the ScienceWorkshop interface to the computer, turn on the interface, and turn on the computer. 2. Connect the Voltage Sensor DIN plug to Channel A of the interface. POWER ScienceWorkshop Connect banana plug patch cords into the OUTPUT ports on the interface. 4. Open the document titled as shown: A B C DIGITAL CHANNELS ANALOG CHANNELS (±10V MAX INPUT) OUTPUT (±5V / 300mA) DataStudio ScienceWorkshop (Mac) ScienceWorkshop (Win) P45 Speed of Sound 2.DS P36 Speed of Sound P36_MACH.SWS The document opens with the Signal Generator window, a Scope display, and a Frequency Spectrum (FFT) display. The DataStudio document also has a Workbook display. Read the instructions in the Workbook. The Scope display will show the voltage from the Output of the interface to the speaker on the Resonance Tube and the input voltage from the microphone connected to the Resonance Tube. The Frequency Spectrum (FFT) display will show the input voltage from the microphone. The Signal Generator is set to produce a sine wave at 1000 Hz. It is set to Auto so it will automatically start or stop the signal when you start or stop measuring data. PART II: Sensor Calibration and Equipment Setup You do not need to calibrate the Voltage Sensor. 1. Set up the Resonance Tube on a level surface. Place the piston inside the tube. Put the piston rod through the hole in the support and mount the tube into the support using the elastic cord. Position the piston at the 80 centimeter mark inside the Resonance Tube. 2. Connect patch cords from the OUTPUT ports of the interface to the speaker jacks on the Resonance Tube. 3. Make sure that a fresh battery is installed in the microphone (part number from To Interface To Interface p PASCO scientific P45

3 Radio Shack, or its equivalent). Place the microphone in the small hole below the speaker. Use the thumbscrew on the side of the speaker assembly to hold the microphone in place. 4. Connect the microphone plug into the Mini-phone-jack-to-BNC adapter cable (included with the Resonance Tube). Connect the BNC adapter cable into the BNC ADAPTER PLUG (also included with the Resonance Tube). 5. Connect the Voltage Sensor banana plugs into the BNC ADAPTER PLUG. PART IIIA: Data Recording WARNING: You can damage the speaker by overdriving it (increasing the amplitude too much). The sound from the speaker should be barely audible. Please keep the amplitude at 0.98 volts. 1. Begin measuring data. (Click Start DataStudio or MON in ScienceWorkshop.) The Signal Generator will begin automatically. The Scope will display the output signal from the Power Amplifier and the input signal from the microphone. 2. Determine the position of the first antinode in the standing wave inside the tube. Slowly push the piston further into the tube. First, listen for an increase in the sound from the speaker indicating that you have produced a standing wave in the tube. Also watch the signal on the Scope display. The input signal from the microphone reaches a maximum when the length of the column of air is adjusted so there is an antinode at the microphone. Finally, check the height of the fundamental frequency in the Frequency Spectrum (FFT) display. 3. Adjust the piston position carefully until you are satisfied that the piston is at the point which produces the loudest sound as well as the largest signal on the Scope and FFT displays. Record the piston s position in the Data section. 4. Continue moving the piston into the tube until you reach a new position where a standing wave is produced. Record this new position in the Lab Report section. Continue moving the piston until you have found all of the piston positions inside the tube that produce standing waves. 5. Click the STOP button to stop measuring data. P PASCO scientific p. 77

5 Analyzing the Data 1. Find the average distance between each piston position. Use this distance to determine the wavelength. (Remember, λ = 2L.) 2. Use the wavelength and the frequency to calculate the speed of sound in air inside the tube. Record your data and results in the Lab Report section P PASCO scientific p. 79

6 Physics Labs with Computers, Vol. 2 Student Workbook P45: Resonant Modes and Speed of Sound A Lab Report Activity P45: Resonant Modes and Speed of Sound What Do You Think? The speed of sound can be determined by various methods. How can you calculate the speed of sound in a column of air inside a tube? Data Position Distance (m) x (m) Average Frequency = 1000 Hz 1. Find the average distance between each piston position. Use this distance to determine the wavelength. Wavelength = m 2. Use the wavelength and the frequency to calculate the speed of sound in air inside the tube. Speed of sound = m/s Questions 1. Use the data that you recorded to sketch the wave activity along the length of your tube with the piston in the position furthest from the speaker. 2. The theoretical value of the speed of sound in air is: m/s x Temperature ( C) m/s. For example, at Temp = 18 C, the speed of sound is m/s. Determine the theoretical value of the speed of sound in air based on the temperature of air in your room. How does your measured speed of sound compare to the theoretical value of the speed of sound? p PASCO scientific P45
