Part 2: Changing Tension 1. Keep the mass on the hanger the same as in Part 1 and adjust the frequency so that the string vibrates in two segments. Now, without changing the frequency, decrease the mass on the hanger until the string vibrates in 4 segments. You may have to use small masses to get a good waveform. Remember that it is more important to have a good node at the end of the blade than to have the biggest amplitude possible. 2. Record the total hanging mass, including the mass hanger. Calculate the ratio of the new mass to the original mass. Why is the ratio not 2? Part 1 Data Table: Suspended mass: 0.225940.!

How is the frequency of the two-segment related to the frequency of the four- segment wave? Is the ratio of the frequencies what you would expect? (Ctrl) answer. 2. Are the speeds of the different modes of the waves about the same? Why? 3. In Part 2 of the lab, why is the ratio of the new mass to the original mass not equal to 2? Using Equations 2 and 3, determine the theoretical value of the mass on the hanger needed for the string vibrates in 4 segments. Determine the percent error of the theoretical and experimental values. ABSTRACT • Objective of lab with brief statement of procedure. • How does the experimental value of mass compare to the theoretical value of mass for the 4 segment standing wave?
