Mirror when placed down shows fliped straight image, but why does the water on ground shows a reverse  image ?

Its all about reflection of light.

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

A mirror CAN make things look upside down.  Stand in front of a mirror and hold a book up so you're reading the cover.  Now, turn the book so the cover faces the mirror and you can see the book cover in the mirror.  Normally you would rotate the book about a vertical axis, THIS is when the left and right reversal takes place.  You could instead turn the book upside down.  Then the reflection of the cover WOULD be upside down, and not backwards.\n\nOther answers given:\nRefraction does not happen. Only reflection.  Refraction has to do with the bending of light when it goes from one medium (such as air) to another medium (such as water).  It has nothing to do with the question.\n\nBecause our eyes are next to each other.  Close one eye and prove to yourself that that answer is nonsense.\n\nAlthough it seems backwards its really not.  Prove this is wrong by holding a book to a mirror and trying to read it.

Because of the coriolis effect. However, this is 100% not true. The water could either flow clockwise, counterclockwise or straight down depending on the shape and curvature of the sink/toilet

THe image formed by a plane mirror has \n\na) the same size\n\nb) is at the same distance from the mirror as the object\n\nC) position opposite to the object\n\nD) kind : if the object is real the image is virtual\n\nif the oject is virtual, the image is real

What you are describing is a result of light reflecting off a concave surface.  The best way to explain this is like this:\n\nDraw a big T on a piece of paper.\nNow draw a line from the lower right side to the vertex of the T (that's the intersect).  This represents light coming in.\nNow draw another line from the vertex to a point at the same location as the origin of the other line, but on the lower left.  That is the light leaving.  The angles of both lines converging on the crossing of the T should be the same.  Same with any beam of light.  It is reflected at the same angle as it is received.\n\nA spoon is a reflecting concave mirror.  If you could get close enough to the spoon you could see your image right side up.  But when you are further out than the focal distance the image inverts because the beams cross over each other.

Because the mirror reflects whatever is directly in front of it.  Your left hand is directly in front of the right side of the mirror.  Your head is directly in front of the top of the mirror.

It could also be the wind going in different directions pushing the top layer of the water in different directions which in turn, gives you different reflections which can appear to be separated.

Mirrors don't actually reverse anything.  When you face someone or something, they have to turn around so that you can see them.  A mirror doesn't have this limitation.  You can see something without turning around to do it.  Of course, this is backwards from what you usually see.  In order to see the front of something, you could turn it around vertically instead of horizontally.  In that case, you could maintain left and right, but you would be confused up and down.

do u mean speed? no, the magnitude is stillt he same but the direction is changed if and only if the mirror has a smooth surface. cause if it is not. there would be many angle of reflection

It's probably the water causing refraction of the scope.  You'll see that at higher magnifications.  I think it's the same principle as a snowflake.

The lens in the eye flips the image top to bottom AND left to right. The fact that a mirror flips left to right and not top to bottom is not really a fact. We are imposing our view of left and right on the reflected image. For example, in a mirror, if you raise your right hand, the hand on the right of the image raises. It is only because we perceive the person in the mirror as ourselves that we say it is raising its left hand. Similarly with text. You are turning the text around to point it at the mirror, and it is reflecting directly. There is no flipping going on. If you write on a tranlucent piece of paper, and hold it up to the mirror with the text facing you, the reflection is the correct orientation.\n\nI know it's confusing, but think about it for awhile, and you'll realize you're assigning your ideas of left and right to the things in the mirror, when really there's no difference left / right or top / bottom to the mirror.\n\nPS - Caitlin has no idea what she's talking about.

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.

hold it up in front of a mirror and look at the image in the mirror through the hole???  LOL.

Mirror?  You mean flip it backwards or something?  Or copy it?

If you are referring to the phenomenon of water actually flowing "uphill"- it is only a myth.\n\nMany have thought themselves to observe such a thing but it is only an optical illusion. Usually the result of objects just below the surface causing a questionable rippling effect that makes the water appear to flow the "wrong" way.\n\nIt's neat to watch though.

The equation which relates the object distance (Do), the image distance (Di), and the focal length (f) of the mirror is\n\n1/Do + 1/Di = 1/f\n\nSolving for the image distance\n\nDi = 1/(1/f - 1/Do) = f*Do/(Do - f)\n\nFor this case, the image will be minified and inverted. FYI, the magnification is given by M = -Di/Do, where a negative value indicates and inverted image. These results can be verified through ray tracing.
