Morphology

corrugation = corrugate (transparent) = corrugate + ation

The noun is a regular formation from the verb 'corrugate' meaning the process or result of corrugating, so the relation is directly derivable.

Etymology

Corrugation comes from the Latin parts cor- and ruga meaning 'wrinkle'. So it means making 'wrinkles' on a surface, which is why a corrugation is a ridge or groove — like the wavy 'wrinkles' on corrugated cardboard or metal.
