If you pluck a guitar string at L/3 (one-third of the way from the end), which partials will be missing and which is likely to be the strongest partial?
a. Any partial with an antinode at L/3 will be missing, the fourth is likely to be the strongest.
b. Any partial with a node at L/3 will be missing; the fifth partial is likely to be the strongest.
c. Any partial with an antinode at L/2 will be missing; the third partial is likely to be the strongest.
