Lab A3: Standing Wave on a String Questions 1. What properties of the string determined its wave speed? Describe what experimental setup Dr. Erenso needed to determine these properties and how those measurements helped you to calculate the wave speed. 2. What value did you obtain for the lowest frequency mode? How do the higher mode frequencies relate to this lowest frequency mode? Based on this pattern, what would you expect the m = 6 frequency to be? Explain. 3. At higher frequencies, the wavelengths got shorter. Explain how you are making sense of this observation? (i.e., why do wavelengths get shorter when the frequency gets higher). Lab A3: Standing Wave on a String Must Haves Goal: Determine wave speed, wavelength, frequency for 15t four modes of the demonstration you saw in Video Clip2. Note: The length of the string from the speaker to the pulley (part of the string where you see the standing waves) is 1.2 m. The mass hanging from the string is 100 gram. Discuss: What information will you need to make those predictions? Must Haves: (All labs must have titles) A sketch of the experimental setup. Record the values of any measurement relevant to the experiment (from the video). A sna shgtwgraph] for each separate mode with clear labelling for the nodes and antinodes, the string length, and the wave en . Make a table that organizes your data and calculations for wave speed, wavelength, and frequency. Value recorded for_the predicted frequencies and the measured frequencies. Note that the measured frequencies are what Dr. Erenso tell you In the Video. Mass (1.47 gram) of 0.97m long string (same kind of string used for the lab in Video CIiQZ.)
