A mirror is an object with a sufficiently polished surface for an image to form by reflection. A mirror is a surface that has the ability to reflect most of the light rays falling on it, and for the surface to have this ability, it must be with a high degree of smoothness.
Scientific definition of a mirror
Science defines a mirror as a glass tool that has the ability to reflect images falling on it by reflecting light. .All these ordinary mirrors that reflect images require the use of visible light, and the mirror in addition to its large ability to reflect light, it also reflects sound.
Mirrors are mainly glass industry, and have many uses in various fields of industry, medicine, traffic, and others…
There are different types of mirrors.
Flat Mirror
It is used in most of our daily needs in order to reflect the image, such as at home for example.
Concave mirror
It is used to enlarge objects; concave mirrors have great magnification power for objects, and they can be made in large sizes to suit their uses. Used in the fields of astronomical observation in telescopes, as well as in the mirror used by the dentist, and mirrors used in the field of cosmetic surgery and shaving purposes,makeup, and others.
Convex mirror
This type of mirrors is used less than other types of mirrors, and this type is used for minimizing things, and in a more correct way give a wider and wider to reflect the image and see the opposite side far more than ordinary flat mirrors, Convex mirrors are used a lot In the manufacture of protection systems, such as devices that prevent theft, it can display more than one angle at the same time, as well as the side mirrors of cars.
Acoustic Mirrors
Acoustic mirrors are also reflective parts like other mirrors, but they are used for the concentration or reversal of sound waves.
Active mirrors
This is the type that is introduced in the manufacture of laser discs.
Cold mirrors
These mirrors have the advantage of allowing infrared light to penetrate efficiently, and then reflect visible light. Cold mirrors can be employed as dichroic beam splitters with laser systems to reflect visible light wavelengths while infrared transmission.
Hot Mirrors
These mirrors do exactly the opposite of what cold mirrors do, they do the opposite of infrared radiation, while allowing only the normal radiation to be carried through them. Hot mirrors is used, for example to serve as dichromatic beam splitters for specialized applications in fluorescence microscopy or optical eye tracking.
X-ray mirrors
These mirrors are used in the field of radiation, where they can give a bright shiny reflection of X-rays.
One-way mirror
One-way mirror is also called two-way mirror. It’s a sheet of glass that can be seen through from one side and is a mirror on the other, used especially for observation of criminal suspects by law-enforcement officials or witnesses.
