釋義

反射的；鏡像

與光、聲、熱的反射或幾何鏡像對稱有關的

describes a shape, pattern, or property that involves, shows, or results from the way light, sound, or heat bounces off a surface, or from the mirroring of a figure across a straight line — for example, a pattern that can be folded in half so both sides match exactly, or a surface that sends back light rather than letting it pass through.
