单词 mirror
释义 mirror
A surface that reflects most of the light falling on it. A plane mirror is a flat surface that produces an erect virtual image of a real object, in which front and back are reversed. Spherical mirrors are formed from the surfaces of spheres and form images of real objects in much the same way as lenses. A convex mirror forms erect virtual images. They are commonly used as rear-view mirrors in road vehicles, and give a diminished wide-angle image. A concave mirror can form either inverted real images or erect virtual images. (See illustrations.) Spherical mirrors obey the lens equation (using the real-positive sign convention) and are subject to some aberrations similar to those of lenses.
