Things That You Need to know about Mirror

What is a mirror: A mirror is a flat and smooth surface which reflects the light when light falls on it? And the reflection of light makes the image. Mirrors are often used to create illusions by the magicians apart from the daily use we have.

Mirrors are of two types

1. Flat mirrors: In flat mirrors the size of the image remains same as that of in the object.

2. Curved mirrors: in curved mirrors the size of the image will be enlarged or diminished as based on which convex or concave mirror are you used.

Uses of mirrors

1. They are used for decoration and are also used to made ornaments.

2. They are used for the personal grooming and to admire one broadly.

3. Convex mirrors can be used as safety in vehicles.

4. They can be used in instruments as well as in paintings.

5. They can also be used in the scientific apparatus like as lasers, telescopes and cameras.

Properties of a plane mirror

1. The image formed by the mirror is not the real image. It is the virtual image.

2. The image formed by the mirror is of the same size as the size of the object. If the object moves two steps forward the image will also move two steps forward and if the object moves two steps backward then the image will also take two steps backward.

3. The image formed by the mirror is lateral inverted. Lateral inversion is nothing it is just as the right side of the image shown in the object is on the left side of the image and vice versa. If you stand in front of a mirror and you move your right hand then the image in the mirror will move his left hand. And if you move your left hand in upward direction then the image in the mirror will move his right hand in the upward direction.

4. So we will conclude that the image formed by the mirror is as far behind the mirror as the object is in the front of it and the right badge appears to seem as left and left seems to be as right.History of mirror: The earliest mirrors were the cut pieces of very shiny metals such as brass and bronze they are even mentioned in “BIBBLE”. Then in the 14th century, a technician invented very crude grass mirrors which reflected the metallic backing. This is made using the technique of amalgam of tin and mercury, eventually, the secret of mirror making spread worldwide. Perfect mirror: A perfect mirror is a mirror that reflects light and electromagnetic radiation and does not transmit or absorb it. The mirrors which we use in our daily life are known as domestic mirrors. These mirrors are not the perfect mirrors as they can absorb a portion of the light which is falling on it.
   

Applications of plane mirrors

1. Plane mirrors are used in periscope.

2. Plane mirrors are used in galvanometer scale.

3. Plane mirrors are used in removing parallax in compass boxes.

Applications of concave mirrors

1. Concave mirrors are used by the doctors to examine nose and throat.

2. Concave mirrors are used as reflector in headlights of a car.

3. Concave mirrors are also used as shaving mirrors.

Applications of convex mirrors

1. Convex mirrors are used as a driver mirror to see the traffic behind.

2. Convex mirrors are used as a makeup mirror. As you can see, that the different types of mirrors have different types of domestic and industrial applications. The installation and maintenance of a mirror depends on the purpose and utility of the same.
