A mirror reflects light in a way that preserves the original image. They are different from other materials that reflect due to the fact that they do not preserve the original waves. Mirrors used most often have a flat surface where the reflect is perfectly symmetrical. Curves mirrors will produce magnified images that distort the reflected images. Mirrors are used everyday for personal use, decoration and architecture. Mirrors are also used in devices such as telescopes, lasers, cameras and industrial machinery. Most mirrors are designed for visible light.
Looking in a mirror, the image will be reversed from the original image. A mirror will reverse the image on the forward and backward axis. Left and right will be defined relative to the front and back of the image. Flipping the image front and back and left and right is equivalent to a rotation halfway around the vertical axis.
