Answer
The "wave" created by the spectators in a stadium is analogous to a transverse wave.
In order to create a wave that is analogous to a longitudinal wave, the spectators should move side to side while bumping shoulders against their neighbors.
Work Step by Step
The "wave" created by the spectators in a stadium is analogous to a transverse wave, like a wave moving along a string. The amplitude of the wave is perpendicular to the wave's direction of motion.
In order to create a wave that is analogous to a longitudinal wave, like a sound wave, the spectators should move side to side while bumping shoulders against their neighbors.
