To look in another direction, human beings turn their heads about a vertical axis.This causes a left-right reversal in the image but not an up-down reversal.To be precise, it reverses the object in the direction perpendicular to the mirror surface (the normal).Because left and right are defined relative to front-back and top-bottom, the "flipping" of front and back results in the perception of a left-right reversal in the image.This kind of glass mirror is produced by coating a silver, copper film and two or more layers of waterproof paint on the back surface of float glass, which perfectly resists acid and moisture.A silver glass mirror provides clear and actual images, is quite durable, and is widely used for furniture, bathroom and other decorative purposes.(If you stand side-on to a mirror, the mirror really does reverse your left and right, because that's the direction perpendicular to the mirror.) Looking at an image of oneself with the front-back axis flipped results in the perception of an image with its left-right axis flipped.

This is different from other light-reflecting objects that do not preserve much of the original wave signal other than color and diffuse reflected light, such as flat-white paint.

Various colors, patterns, and glass shapes are available.

Such a glass mirror is durable and more moisture resistant than ordinary printed glass and can serve for over 20 years.

When a person looks into a mirror, the image is actually front-back reversed, which is an effect similar to the hollow-mask illusion.

Notice that a mirror image is fundamentally different from the object and cannot be reproduced by simply rotating the object.

A beam of light reflects off a mirror at an angle of reflection equal to its angle of incidence (if the size of a mirror is much larger than the wavelength of light).
