-
Mirrors have a thin metal layer behind glass that reflects all light.镜子在玻璃背面镀有一层薄金属膜，能反射所有光线。
-
White light contains all colors, and mirrors bounce them back equally.白光包含所有颜色，镜子会将它们等量反射回来。
-
No color is absorbed or filtered, so what you see stays true.没有颜色被吸收或过滤，因此所见即真实。
-
Glass protects the metal and helps light enter evenly.玻璃保护金属层，并帮助光线均匀进入。
-
A flat mirror keeps light rays in order, so images look natural.平面镜保持光线有序反射，使成像自然逼真。
-
Curved mirrors bend light differently but still keep color accurate.曲面镜虽以不同方式弯曲光线，但仍能准确还原色彩。
-
Even old mirrors reflect color well if the metal stays clean.只要金属层保持洁净，老式镜子也能良好反射色彩。
-
This makes mirrors perfect for science tools and daily use.这使得镜子既适合科学仪器，也适用于日常使用。
