Venn diagrams are used for comparing and contrasting topics. the overlapping sections show characteristics that the topics have in common, and the sections that are unique to each topic show the characteristics that apply to only that topic. this venn diagram is comparing longitudinal waves and transverse waves.
“parallel” and “perpendicular” are switched.
the slinky descriptions of motion are switched.
particles travel along the wave in longitudinal waves.
particles move long distances in transverse waves.

The correct answer is "the slinky descriptions of motion are switched".

Explanation:

Longitudinal wave: The particles of the medium move parallel to the direction of the motion of the wave in which the energy from one particle to the another is transported. For example, sound wave. Here, the motion of the wave is like back and forth.

Transverse wave: The particles of the medium move perpendicular to the direction of the motion of the wave in which the energy is transported from one particle to the another.  For example, light wave. Here, the motion of the wave is like up and down.

Therefore, there is an error in the given Venn diagram. The slinky descriptions of motion are switched.
