This experiment studied standing waves on strings by measuring the relationship between wave velocity, string tension, and other factors. Three parts were conducted: 1) measuring the period of a simple pendulum at various lengths to determine the effect of length on period, 2) finding the period of a physical pendulum at different angles, and 3) examining coupled pendulums in different normal modes. The results were analyzed to calculate the acceleration due to gravity and percent error. While the data followed expected trends, some discrepancies were due to imperfect measurements and friction. Overall, the experiment demonstrated how string properties influence wave properties.
