Write down a general expression relating the number of nodes in a standing wave to value of n.
Write down a general expression relating the number of antinodes in a standing wave to the value of n.
Imagine that you have a string of fixed length that has a standing wave on it that has two segments, n=2. If you were unable to change the frequency of your generator, how could you change to a standing wave with n=4?
In part 2, is the speed of the wave the same in each trial? Why or why not?
We are using a string that does not stretch. What would happen in Part 2 if the string was stretchable?
