1. Parallax plays a part in measuring the internodal distances in Part 2. Describe in detail how measurements were made to minimize this effect. If an amount of uncertainty in measuring the internodal distances is to be considered what would be a reasonable amount. Explain why this amount was chosen.

2. If a thicker string was used in this experiment how would this affect the different parts of the experiment? Which quantities would be affected and how would they be affected?

3. As you increased the tension on the string in part 3 it may have caused a minor stretching of the string, thus lowering the linear density of the string. How does this affect the slope of the line drawn on the graph compared to using an ideal string which does not stretch

4. Using equation 2 determine the velocities of the waves on the string for each of n = 3.5, 2.5, 1.5, and 1.0 from part 3. (show work)
