Why is it when I look in a mirror that left is right and right is left, but up is not down and down is not up?

Please,ask your friend to stand beside the mirror.And to look yourself in the mirror you stand opposite to the mirror.Now look at your friend first,you notice that your friend`s right hand and your left hand are on the side.Rise your left hand, simutaneously  hand at the right side of the image will rise to the same position.Then ask your friend to rise  his  right hand,there is no difference between the side of hand of the image and hand of your friend.But  there is difference between your hand and of the image. This is becuase you are facing opposite to the mirror.That is 180 degree angular difference horizontally  is there between you and the mirror as you and the mirror are facing opposite to one another.once again look your friend, check the vertical difference, that is head & legs of your friend  that are at the same position as of yours.This is because there is no vertical angular difference between you and your friend.Same applies to the mirror.Further ask your friend to turn 180 degree horizontally at the same place. Then your friend also facing opposite to the mirror, same as you are facing.Notice that there is no remarkable change in the  position of your heads and the top of the mirror.

You see a mirror in a mirror in a mirror in a mirror ......\nThere are various gadgets using this effect. \nFor instance if you put a lightbulb between the two mirrors and look throug the one way mirror you will see (depending how parallel you've managed to put the mirrors) lots of lightbulbs disappearing into infinity. I know 'cause I've done it!

Gravity,it is often diffacult to tell which direction you are faceing, the teory is to whatch the saliver to see which way it goes.so you digg in the opposite direction and not bury your self ferther

When we say UP or DOWN, knowingly or unknowingly we are saying UP refering to a constant point or fixed reference. "I am going up to get my toolbox" .. you are really saying I am going in an upwards (z-axis) direction from a certain point (downstairs). Same thing with left of right.. When someone says "go down the road and take a right turn".. Say the road is North Main Street.. you go down and take the first lane that goes in the right direction. now if someone is coming from the opposite direction (South Main) the right lane becomes the LEFT lane for him. so its bascially where you are looking from.  \n\nSpace is infinite.. yes. and like being on earth.. Going UP or DOWN or LEFT or RIGHT would be going in a specified direction keeping something constant. Space has not been proven to be greater than 3 dimensions, hence it technically can be plotted on a x,y,z grid. e.g Sun being the center (hypothetically) (0,0,0).  so anything above our Sun would be in the UP direction then.\neven if it was a 4 dimensional sphere, it would have up, down, left, right, backward, forward, u, v, w, x, y, z directions\n\nu,v,w,y,z directions are called (kata, delta, zant, ana, upsilon, wint)\n\n;)

Why do we appear backwards in the reflection of a mirror? How do we see our true image?\n\nWebsite below has the answers.

It's actually happened to a lot of women. I heard it was normal because it happened to me. My right is slightly bigger than my left, but you have to look for a long time to notice. I wouldn't worry about it.

A mirror preserves absolute direction, both horizontally and vertically.  Say you're facing west; the reflection of your north hand is on the same side of the room as your real north hand -- namely the north side.  And the reflection of the top of your body is toward the ceiling, just like the real top of your body.  That's because north vs. south and up vs. down are the same for everybody.  But right and left are not absolute directions.  Your north hand is on the right because you're facing west.  If someone were facing east, their north hand would be on the left.  And your reflection in this example _is_ facing east because you are facing west, and the reflection is looking back at you.  So, your reflection's north hand, which is the same as your north (that is, right) hand, is its left hand.

Not necessarily though, dyslexia is a disorder where the mind twists the letters in different orders, not recognizing the proper oder, or the correct letters.... not just putting them backwards like yours are.  I could read your question because I have read mirror writings before, it is just words, phrases and sentences written backwards just like you did on here!  I thought it was creative...  Good job!  :0)

there is no up or down.

It stays up in the main bathroom. In my bathroom it stays down. \n☺

Well it depends on your frame of reference... it spins from west to east so if you were looking down on the earth from above the north pole then it's anti-clockwise. If you look from south pole, it's clockwise.

It does neither. It just reflects a laterally inverted image which has nothing to do with left-right or top-bottom.

This is due to the optics inside of a microscope.  Look in any biology book on the chapter about microscopes and they'll probably have a cross section of how microscopes work.  If you trace the light rays, you will see that they object will definitely be upside down, most likely due to a concave lens or combinations of convex and concave lenses inside the lens system (microscope).

This could happen one of two ways:\n\n1) The mirror is made of another material than glass or the usual material used.\n\nOR\n\n2) The mirror has curvatures somewhere along the way creating a distorted image.\n\nHope this helps!

Not to sound like a nerd, but since it is at an angle higher than that of your face, it reflects your light pattern (Your face) in an upside down angle. To make a long story short, its like a fun house mirror. Try tilting it at different angle and maybe you will see yourself right side up!

That caved-in side of the spoon is "concave" and the other side is "convex".\n\nYou can see yourself upside down in any concave shaped mirror, when your distance from the mirror is favorable for that to happen.\n\nGet one of those so called shaving mirrors ans stand at different distances from it and observe the results.

They are almost the same size, you are right  - the reflective image is smaller. The reason it looks bigger is because you are looking at a more or less 2-dimensional image. You have to physically look from the top to the bottom. I don't know if this is a good example, but think of a hockey goalie protecting his goal. The further out he moves, the more of the goal he covers. He looks like a giant to the shooter because he has to move his head to see from his head to his feet. \nHere's one for you - how large vertically does a mirror have to be in order to see your total reflection? It doesn't matter how far away it is?
