Vibrating String Lab Questions 1. Choose all statements below that are correct. (more than one is correct) The fundamental frequency of a vibrating string increases as a. The tension increases and the density decreases b. The tension increases and the length increases c. The tension increases and the density increases d. The tension increases and the length decreases ANS=__________ 2. Which image below represents the 4th harmonic for a vibrating string? ANS=__________ 3. Which graph is the best represents data from an experiment that shows how the fundamental frequency of a string depends on string length? ANS=____________ (next page) Measurements are taken to see how the period of a mass spring system changes with the mass on the end of the spring. A data table is shown below. Mass (g) 50 100 200 400 Period (s) 1.00 1.41 2.00 2.82 This data suggest that the Period is a) Proportional to the mass b) Proportional to the square root of mass c) Proportional to the mass squared d) Inversely Proportional to the mass e) Inversely Proportional to the square root of mass f) Inversely Proportional to the mass squared
