Mirror

From Zelda Wiki.org

Mirrors are devices used in minor puzzles in many dungeons throughout the Zelda series. They usually involve reflecting light at a target. They may also involve multiple mirrors reflecting one beam of light. The puzzle is angling the mirrors in the correct way so that the light reaches the target.

Link also wields the Mirror Shield which acts like a mirror.
