Why do mirrors reverse an image horizontally and not vertically?
108047
reality (the first answerer) is mostly correct, but it's more of a phychological effect than an optical illusion. When you look in the mirror and raise your right hand, it looks like "the guy in the mirror" is raising his left hand. Because of this, you perceive the mirror to be flipping left and right. But all the light is just being reflected directly back. If you hold writing up to the mirror, it looks backwards left to right. If you hold it vertically, it looks backwards top to bottom. There is no left-right top-bottom asymmetry. Think about it for awhile and you will realize that a mirror doesn't "flip" anything, it's all in your mind.

this tessellation is both a rotation and translation...there is no reflections here...basiccally you notice that you can shift the shape to various places on the tessellation and have it reoccur...this is called translation.  you also notice that if you change the orientatoin of the shape...for instatnce...rotate it you find several occourances found on the tessellation\n\nhowever, this shape does not reflect because it is not symmetric anywhere.\n\nhope this helps, matttlocke

Hopefully this will help you. I can't say I understand it real well, but it is a way to get vertical data to appear horizontal I think.

Light reflected from surfaces like a flat road or smooth water is generally horizontally polarized. This horizontally polarized light is blocked by the vertically oriented polarizers in the lenses.\n\nThe result: a reduction in annoying and sometimes dangerous glare.\n\nsee the link for a more scientific discussion on polarization

The glass is poured to the desired thickness, and then silver is applied to the back to give it's reflective surface.  It is then coated with another substance to prevent the light from passing all the way through.  You then see your reflection.\nIn a piece of two way mirror, the silver is applied to the front of the mirror and the other non-reflective substance is omitted.  Thus, you can see all the way through.\nOne good way to tell if you are looking at a piece of two way mirror, is to put your finger up to the glass.  If there is no 'space' between the tip of your finger and the glass...it may be 2-way.  If there is a 'space', it may be only one-way.\nNext time you go into a store, look around for mirrors that appear in the most unusual places.  More than likely, these are 2-way.

What you see in a mirror depends on how the light bounces off the mirror and into your eyes. When light hits a mirror, it bounces off in the same way that a ball would bounce off the mirror. If you threw a ball straight at a flat mirror, it would bounce straight back. If the mirror was curved so that the ball struck the surface at an angle, it would bounce away at an angle. \n\nWhen you look into an ordinary flat mirror, the image of your face is right side up: Your hair is on top of your head and your chin is underneath. To reach your eyes, the light from your hair hits the mirror at a slight angle and then bounces into your eyes from above - which is why you see your hair on top and your image as right side up. \n\nAs everyone knows, a flat mirror reverses your right side and your left side. How does it do that? Suppose you are standing face to face with another person. If your right ear points toward the east, his or her left ear will point toward the east. Now, instead of facing another person, suppose you are facing a flat mirror with your right ear pointing to the east. The light from your right ear will bounce off the flat mirror and enter your eyes from the east. Even though your east ear is the east ear of the image, your right ear has become the left ear of the image! (Yes, this is a little mind-boggling at first reading. But once you get it, it will seem simple.)

An object is symmetrical if it could be cut down the middle and produce two mirror images.  "Bilateral" just means "two sides", indicating that the object is symetrical in one direction.  The term is used in biology, and is a common trait of the animal kingdom.  \n\nFor instance, look at yourself.  You have one eye on either side of your nose, one ear on either side of your head, one arm on either side of your shoulders and one leg on either side of your hips.  If you took a picture of yourself and cut it down the middle, from top to bottom, the two pictures would be mirror images of one another.  This is bilateral symmetry, the same on both sides.

The phenomenon of left appearing right and right appearing left on reflection in a plane mirror is called lateral inversion.

We see images in mirror. Similarly we see pictures in T.V screen, Cinema screen, and in computer screen.  All we see in a single plane surfaces. \n\nConsider the moment, when all pictures seen in them are still including the image in mirror.\n\n To view them leisurely, we take photos of all and print them and paste them all in their position. \n\nWhat is the difference between the previous one and the present one?\n\nBoth are in the single plane. Behind the plane there is wall or some electrical gadgets only.\n\nIf images in mirror are three dimensional then all pictures and the drawings in the books will be three dimensional. However, we try to give the three dimensional effect in picture drawn on a plane paper. A cube can be drawn in a paper and can be visualized in three dimensions. That does not mean that the drawing is three dimensional.\n\nBut real images can have actual three dimensions. In that case we say it is a three dimensional image.  But the real image formed in a camera screen is two dimensional.\n\nHence all virtual images are two dimensions only even though they appear to be three dimensional. \n\nReal images can be either two dimensional or three dimensional. \n\nReal images are only images and are not real objects even though they are three dimensional images.

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.

if you want to open an image file, and mirror it, you're going to need a art package, like jasc paint shop pro - or adope photoshop...  if it's just a JPEG or BITMAP image.. you can open it in MICROSOFT PAINT (go to IMAGE on the top toolbar) and go to FLIP / ROTATE

Your telescope is a reflector. Light enters the tube, and strikes the primary mirror in the back, which is parabolic like a satellite dish. The mirror directs all the light it could gather to the secondary mirror upfront. If you could see the light being directed to the secondary mirror, it would appear as a cone with the tip chopped off due to it striking the secondary mirror.\n\nThe primary mirror, being parabolic, flips the image when viewed from past a certain distance away, because of the way it directs the light. If you ever come across those magnifying beauty mirrors, it's the same deal. You'll find that at a certain distance, the reflection of your finger appears on the opposite side that your finger is actually on. You can even find a point where your finger and it's reflection is pointing right at eachother and you can't tell the difference between which is the real object and which is the reflected image!\n\nAnyway some people are bothered by the fact that the image is "upside down" in reflectors and there is a way to correct for it, as other people have mentioned. But keep in mind that in space, there is no up or down, so there's no such thing as upside down. You really get used to it quickly when aiming the telescope on things and recentering objects.

Photos capture an image of light.  And mirrors essentially reflect photons. We know that photons, particles of light, have wave/particle properties and when they are reflected off of an object, they are affected by the surface of the object of mirror. Look at your self on both side of a spoon.  The concave part, the one that is curved in, should have an upside down version of you, and on the otherside, convex, you will have an elongated version of yourself.  \nIf you look at the queston from a quantum phsyics perspective.  Every time you look in the mirror, you will see a different you. This is because you are actually seeing different light reflecting off a different surface.  \nI really dont know much about cameras, but thank God for photo shop.  Mirrors are a bad invention in my opinion.  People get caught up in having to maintain an external image that the rest of the world sees, when in reality the image of ourselves that we should really work on is the one inside our heads.  Anyways, I hope I answered your question to some extent.

If you look at a painting from 3 inches away, it will be clear, but a mirror is not in fact a flat image like a painting.  The light in the mirror comes from the surroundings, so, depending on the distance between an object and the mirror, the light travels different distances.  Try standing in front of the mirror and covering one eye-- what you see, in the mirror or not, will be flat.  Uncover the eye and you will have depth perception even when you look in the mirror.

I am not sure what "tise" is, but almost any photo editing software gives you the ability to reverse the picture. I would check your software, im pretty sure you should have that capability. Good Luck!!

Select the object or image and then press the modify menu, transform, flip horizontal.\n\nso in the menu bar - Modify > Transform > Flip Horizontal.\n\nWould have been much easier if it said mirror :P I just figured that one out for you. I might muck around with it now. Hope this helps.
