On the window, I saw the mirror opposite reflecting the wind and water.

A mirror is an object with a smooth surface and can reflect light. The most common mirror is a flat mirror, which people often use to tidy up their appearance. In science, mirrors are also commonly used in telescopes, lasers, industrial instruments and other instruments. Metal devices with regular reflective properties and glass or metal products coated with metal reflective films are often inlaid with metal, plastic or wooden frames. Mirrors are divided into plane mirrors and curved mirrors. Curved mirrors can be divided into concave mirror and convex mirrors, which are mainly used as dressing mirrors, furniture accessories, architectural decoration parts, optical instruments, solar cookers, reflectors for headlights and searchlights, reflecting telescope, car rearview mirrors, etc.
