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
mechanical and electromagnetic waves.
