What is the most accurate physical analog for a particle in a box?

a. A guitar string
b. A rope driven with a sinusoidal oscillation on one end and fixed on the other end
c. A pan-flute pipe (open on both ends)
d. An organ pipe open on only one end
e. A jump rope with a girl on each end driving the end to a rhythm


a.
A particle in a box should be described by a wave function that shows a probability approaching zero at both ends of the box with a ground state maximum at the center. A guitar string is fixed on both ends and cannot vibrate at the ends, but does so at a maximum amplitude in the center.
