how is a mirror important?

*It allows a laser to be viewed - light from the laser cannot be viewed unless it's bouncing off a mirror - a mirror reflects and refracts light\n\n*Allows us to view things from a variety of angles (car mirrors, periscopes, etc)\n\n*Personal hygeine?\n\n*Decorative

A mirror reflects light.  Light from an object strikes the mirror and changes direction so that the angle of incidence equals the angle of reflection.  As a result, light appears to come from behind the mirror, at an apparent distance equal to the distance they are in front of the mirror.\n\nI see no connection to the Boognish.

Early mirrors were usually a sheet of polished metal, often silver or copper, for example the Aranmula kannadi.\n\nMost modern mirrors consist of a thin layer of aluminium deposited on a sheet of glass. They are back silvered, where the reflecting surface is viewed through the glass sheet; this makes the mirror durable, but lowers the image quality of the mirror due to extraneous reflections from the front surface of the glass. This type of mirror reflects about 80% of the incident light. The "back side" of the mirror is often painted black to completely seal the metal from corrosion.\n\nSilvering is the chemical process of coating glass with a reflective substance, originally silver, in order to create a mirror. Today, powdered aluminum or other compounds are more often used for this purpose, although the process maintains the name "silvering

Get a new mirror..that one is an a-hole!

Any material which may have a reflective surface may be said to be a mirror when it does -- be that a silver-backed glass mirror in the Versailles Salon de Glaces, a sheet of gold leaf on the ceiling of Catherine's boudoir in the Winter Palace, the polished bronze shield which allowed Perseus to see not Medusa but her reflection, an ancient Egyptian obsidian obelisk, the Reflecting Pool on the National Mall, the cornea of the human eye...

One-way mirrors are actually just glass coated with less reflective material, known more scientifically as half-silvered mirrors. The result is that only about half of the light is reflected from the glass on either side. But by placing the glass between a dark room and a bright room it effectively becomes a one-way mirror. On the brighter side, the half reflected imaged is far brighter than the half transmitted image from the other side, all we see if the reflected image. On the darker side, the transmitted image is far brighter than the reflected image, so you see whats on the outside. If you simply reversed the lighting, the effect would be reversed.\n\nThis is similar to sunglasses which allows the wearer to see out but hides the wearers eyes. Also observable in home windows at night. In a brightly lit room, the reflection will be seen easier than whats outside if there's no lighting outside.

Ha!  I know just what you mean.  Basically a reflective surface reflects everything and most everything is visible depending on your position in relation to the object.  For example, an object held behind your back can be seen by a person standing in front of you if they change their position slightly.  It is a fascinating and wonderful phenomenon.

When you look at yourself in the mirror the right side of your reflection is to the right of the mirror, and so on left to left, top to top...  What is reversed is front to back.  If you are looking north your reflection is looking south.  Since you and your reflection are looking in opposite directions but the hands are on the same sides your reflection appears left handed because you expect the right hand of a person facing you to be on the opposite side.

A mirror is a surface with good specular reflection that is smooth enough to form an image. The best known example is the plane mirror. The most common use is in the home for personal grooming but mirrors are also used in scientific apparatus such as telescopes and lasers, and in industrial machinery.\n\n\nIn this diagram plane waves reflect off a parabolic mirror to form waves converging onto a focal point.In a plane mirror, a parallel beam of light changes its direction as a whole, whilst still remaining parallel; the images formed by a plane mirror are virtual images, of the same size as the original object (see mirror image). There are also parabolic concave mirrors, where a parallel beam of light becomes a convergent beam, whose rays intersect in the focus of the mirror. Finally, there are convex mirrors, where a parallel beam becomes divergent, with the apparent intersection occurring behind the mirror. Note that spherical concave and convex mirrors do not have a single focal point, as often described in high school physics text books (see spherical aberration in lens (optics) and aberration in optical systems).\n\nA beam of light reflects off a mirror at an angle of reflection that is equal to its angle of incidence. That is, if the beam of light is shining on a mirror's surface at a 30° angle from vertical, then it reflects from the point of incidence at a 30° angle from vertical in the opposite direction.

1) mirrors used on a blind corner turnings to see whether any object is approaching on the other side..\n2) small mirror-sections placed inside the rear view mirrors in big trucks (for Eg) to see vehicles coming on the blind angles of the vehicle..\n3) funny mirrors used to make funny reflections of your body..kept in amusement areas..

If your question is such that the mirror is reflecting the immage off of a T.V. screen. How is that reflected image clearer?\n\nMy answer could be simple. If you have the same resolution and a smaller immage, it will be clearer. In a sence you are taking the immage on a T.V. and stretching it. But on the mirror it is much much smaller so the resultion is better!

It depends on the length of the mirrors.

Generally household mirrors are a highly reflective silver.  \n\nAnything that is highly reflective can be considered a "mirror" (like the smooth waters of a pond, or a shiny black rock).  More than color, it is smoothness that matters in making a mirror.\n\nA porous surface scatters light in many directions while a smooth surface will reflect light back in a single direction, hence the "mirror" effect.

If you try to mirror others, you'll eventually lose all sense of yourself. AND, besides, it is just not possible to be all things to all people.\nIn short, "to thine own self be true." In the long (and short) run, you'll be a lot happier and certainly more satisfied.

When mirrors were new they were very expensive. Only the very wealthy could afford them. If a servant broke one the master or Mistress would cause them so much grief that mirrors were considered  bad luck. The owners encouraged this so that the servants would be more careful. Like most superstitions this one is a way of making people aware of a danger that mignt not be paid attention to unless threatened with bad luck.

sure its called a mirror

I see your point. But without mirrors we wouldnt have lasers, telescopes or rearview mirrors on vehicles. Television media, in my opinion is the biggest reason for vanity and stereotyping.
