Reflection and optics with 鏡
鏡 refers to an object that reflects light to show one’s image, as well as a standard or model that serves as a basis for sound judgment.
Etymology
This kanji is a phono-semantic compound comprised of 金 (metal) as the semantic component and 竟 (end / complete) as the phonetic component, giving the on-reading キョウ. These invoke imagery of metal polished all the way to a finished, bright surface until it reflects a person’s form like a mirror.
Early mirrors were made from polished metal, so 鏡 first named a reflective object and then expanded to optical tools such as glasses, telescopes, microscopes, and scopes.
