Surface Wave (APEX)
Interface
As a mixture is a combination of two or more materials, each of the materials is a phase and then there is the boundary between the materials, the interphase.
contact
Convergent on the western perimeter, divergent on the Easter perimeter.

contact
It occurs when light traveling from one medium to another is completely reflected at the boundary between the two materials. The angle of incidence must be over a certain value (depending on the optical properties of the materials at the boundary).
A boundary is a restriction, a line of demarkation. That fence is the boundary between our property. The ball went outside of the boundary.
divergent boundary
It's the line (boundary) between two countries.
A boundary between two states or nations is a defined line that separates the territories of each entity. It is established through agreements, treaties, or natural geographical features and helps regulate the jurisdiction of each state or nation in terms of governance, security, and administration.
The question is too vague for a definitive answer; depending on context, "surface", "interface", or even just "boundary" might be used.
Convergent boundary's.
