A mirror always tell the truth !!!

It is often said that a mirror doesn't lie. In other words, it shows us what we actually are. But this saying holds good only, at most, for normal plane (flat) mirrors which reflect a beam of sunshine in mere one. direction rather than either scattering it widely in many directions or absorbing it. In this respect, any shiny metal surface like chrome steel acts as a plane mirror... However, more commonly. in our day-to-day life, we use mirrors made from clear flat glasses, provided on their one side with a deposit of pure silver, protected by two layers each of shellac (or corporal varnish) and minimum. This treatment equips the glass with the property of unidirectional reflection of a beam of sunshine.

Man has defied the above-age old saying about mirrors in some ways. for example, by arranging two or more plane mirrors at different angles before an object we can see not one but several virtual images. it's a typical trick played in cinematography showing several pictures of an actor, simultaneously. One can try it out reception holding two mirrors at suitable angles. Even in an exceedingly single plane mirror one sees actually the reversed image of the thing. a straightforward to catch example of the phenomenon is that the image of numerals on the amount plates of the car behind, as seen in your Rear View Mirror (RVM). Also, the RVM shows more distance between your car and therefore the car behind than the particular, which can be elusive while moving the car in reverse gear.

In comparison to the plane mirrors, spherical mirrors exhibit even more interesting illusions. These are either concave (curved inwards) or convex (flexed out). If you stand before a convex spherical mirror, your reflection within the mirror shall be seen much shorter or shrunk. The reverse occurs when an object is placed before a concave spherical mirror. The reflection here appears much enlarged. Not only this, by adjusting their degree of curvatures and distorting the spherical mirrors into cylindrical mirrors, the enchanters within the amusement parks often show their audiences their inverted and eerie (strange, disturbing, and frightening) virtual images that are sure to force them to either laugh or scream, because the case is also. (Remember the film Satyam-Shivam-Sundram supported the eerie images in spherical mirrors). Further, the filmmakers use several, small convex mirrors posted on the ceiling of a space to indicate numerous very small images of a dancing actor in a lovely pattern.

Not just for entertainment. the spherical mirrors are accustomed from several utility articles. The shaving mirrors and structure mirrors are frequently made as concave mirrors since these display enlarged images of the face for more accurate shaving and structure. Likewise,  since the convex mirrors display shrunk images, these are. wont to make Store Surveillance Mirrors which accommodate a larger field view of the shop with small images of the articles for faster monitoring. These also are called Wide Angle Mirrors.

 

Do you still feel the mirrors never lie??
