waves waves waves?

The following are examples of different types of waves: water waves, earthquake waves, light waves, and a wave on a slinky. Which wave is the least like the others? Why?

well, what i do know…is that water waves are cyclinerish, light waves are transverse and waves on a slinky is compression

light waves because they are a part of the electromagnetic spectrum. they don’t need matter as a medium to travel through either.
