The diagram shows schematically the electric field of an electromagnetic wave corresponding to light traveling in air () and after entering a piece of an unknown material. Using the diagram, estimate the index of refraction of this material.

The Santa Workshop Gift Tracker helps Santa’s workshop manage holiday gift production. All system users have an account with a unique ID, name, and email. Elves log in to start gift requests, submit gift builds, and view workshop statistics. A Gift Request is created for a specific child and includes a gift type and priority. Elves may submit multiple Gift Builds for a request. Each gift build belongs to exactly one request, and if a gift request is deleted, its builds are also removed. Gift requests are grouped into Toy Categories (e.g., Educational, Outdoor, Plush). Categories exist even if they have no gift requests, and a request may belong to multiple categories. When a gift build is submitted, the system evaluates it using a separate quality-checking service. After a request is prepared for delivery, the system sends a QR code confirmation to the user through an external messaging service. Given the above scenario, which relationships best fill in the blanks in the diagram? Use the component options above to answer the question. The direction of the arrows dont matter for this question
