    Ok, I know this may sound weird but I have a question about eyes. I was just laying in bed watching tv and had a bottle of water, I held it so I could see through it into the tv and the picture I saw through the water was upside down and backward. Why?

    reflection

    In fact, the eye receives images inverted, and the brain has to flip them. I wouldn't know why the water bottle flipped the image rather than distorted it though. Google is your friend :)

    The angles of a cylinder bend the light, and if things are set up correctly, will invert an image.

    I think that's how it works at least.

    I would imagine that the cylindrical bottle is acting as a lens, which is refracting the light and inverting it (the focal point of the 'lens' must be near your eye).

    EDIT: Here's a tip. Hold a bottle full of water horizontally up to your face and show it to people. You'll look just like an anime character. Now dye half of your hair purple and go to Tokyo.

    Oh I see, the bottle was close to my eye. I was just wondering why that was happening. About the anime character, somehow I don't think that would work out:crazyeye:

    Tell me how google is able to find the answer.

    search water bottle refraction or water inverting images or somesuch

    not so hard

    And in case someone doesn't know that's what's causing it? :mischief:

    At what angle were you looking through it? Along the axis of the cylinder, with it held upright, or horizontal? What was the water bottle made of? How thick were its walls? Were you looking through water in it, or air?

    /me ponders about refractive indeces...

    Don't listen to any of this so called science. The image gets flipped upside down due to Intelligent Invertage.

    See in any medium the angle of refraction can bend the light in such away that it can inverse the image if it is great enough.

    This is a simplification but it goes something like this.



    But it's all lies anyway, the FSM inverts light with his noodly appendages. Just like he diverts the light from data about dinosaurs and stuff.

    Huh?

    Um...lets see here...it was held upside down, plastic, not very thick (it was an Ice Mountain bottle), looking through water.

    Intelligent Invertage as described in the Inverse Bible (or 'Elbib').

    He was joking, it's all just physics. Boring old plain old refraction.

    Pull up google on your browser, and look at your computer monitor through the water bottle at close range, and the answer will appear...inverted, naturally. ;)

    Alright, so its 'refraction'.

    Isn't refraction the bending of light into the colours of the spectrum? Or does it cover this as well?

    slip of the...well I guess it's not a tongue....


    and Swedishguy, I think "water inverting images" is pretty easily understood by the first post, since it's a water bottle.

    Refraction is the changing direction of an wave due to a change in its speed - the speed of light in water is less than air. The index of refraction (inversely proportional to the speed of light in the medium) is a function of frequency, so different frequencies of electromagnetic waves have different indexes of refraction in the same medium - thus, light of different frequencies will bend with different angles and seperate.
