Mirror never tell a lie. Mirror widely used now on. Rear-view mirrors are widely used in and on vehicles (such as automobiles, or bicycles), to allow drivers to see other vehicles coming up behind them. Some motorcycle helmets have a built-in so-called M.R.O.S (Multiple Reflective Optic System): a set of reflective surfaces inside the helmet that together function as a rear-view mirror. There exist rear view sunglasses, of which the left end of the left glass and the right end of the right glass work as mirrors.
Convex mirrors are used to provide a wider field of view than a flat mirror, and are often used on vehicles, especially large trucks, to minimize blind spots. They are sometimes placed at road junctions, and corners of places such as parking lots to allow people to see around corners to avoid crashing into other vehicles or shopping carts. They are also sometimes used as part of security systems, so that a single video camera can show more than one angle at a time.
Mouth mirrors or “dental mirrors” are used by dentists to allow indirect vision and lighting within the mouth. Their reflective surfaces may be either flat or curved. Mouth mirrors are also commonly used by engineers to allow vision in tight spaces and around corners in equipment.
Just like a mirror use in many areas, take time to read many recommended book. Make it easy to see inside of us, just like mirror.
