How is a one-way mirror made and what materials are used in its construction?

A one-way mirror, also known as a two-way mirror, is made by coating one side of a glass pane with a thin layer of reflective material, such as aluminum or silver. This allows light to pass through from one side while reflecting light from the other side, creating the illusion of a mirror. The construction of a one-way mirror typically involves using a glass pane, a reflective coating, and a protective layer to ensure durability and clarity.
