When we are looking through a magnifying glass from a position far away from the focus , a real image is formed which is inverted.This inverted image cannot be obtained on the screen.Hence we see the image upside down. However if we look through the magnifying glass at a position between the optical centre and focus a virtual,erect and magnified image will be formed.This can be obtained on the screen.

Why don't you see things upside down if that how it enter your eyes?

It is true that the images formed on your retina are upside-down. It is also true that most people have two eyes, and therefore two retinas. Why, then, don't you see two distinct images? For the same reason that you don't see everything upside-down. One of our most remarkable tools - the brain - is hard at work for us at this task. Processing visual information is a complex task - it takes up a relatively large portion of the brain compared to other senses. This is because your brain performs several tasks to make images 'easier' to see. One, of course, is combining the two images, which is helped by the corpus callosum, the tiny part of your brain which joins the two big hemispheres. The other part is handled in the optic part of your brain itself, and part of its job is to make images right-side-up. It does this because your brain is so USED to seeing things upside-down that it eventually adjusts to it. After all, it's a lot easier to flip the image over than it is to try and coordinate your hands and legs with an upside-down world! As a result, though, it is believed that for the first few days, babies see everything upside-down. This is because they have not become used to vision. Your brain CAN be retrained though. In one psychological study, participants were asked to wear inverting lenses - lenses that invert the image BEFORE they get to your eye, so that when your eye inverts it, it's right-side-up. At first, everything appeared upside-down to the participants. But, after a few days, people began to report that everything appeared right-side-up! As a second part of the study, the people were asked to take the glasses off. Because they were now used to the lenses, their NORMAL vision appeared upside-down!! Within a day, though, their vision returned to normal. The reason you don't see everything upside-down, then, is simply because it's easier to think about right-side-up!


Does the anatomical position change if the body is upside down?

If the body is upside down then it is no longer in the anatomical position. But no, it would not change.


What part of the eye focuses the light that comes through the eye?

The answer to this question is the retina .......... It's the retina because everything is upside down, bends, goes up to the brain and flips it around........and that is why the light is always focused on the retina


Is Uranus an upside down planet?

Yes, Uranus is often described as an "upside-down" planet because its rotational axis is tilted at about 98 degrees. This means that during its orbit around the Sun, Uranus appears to be rotating on its side.


Why does it not matter that the image produced by a telescope inverted?

One of the most surprising discoveries first-time telescope owners will find is that images may appear upside-down or backwards depending on the type of telescope. The first thought is the telescope is broken - when in fact it is working perfectly normal. Depending on the type of telescope images may appear correct, upside-down, rotated, or inverted from left to right. Why is this? Why would I want to see everything incorrectly? For astronomical viewing, it is not important whether an object is shown correctly. In space there is no up or down. Besides, Saturn is not something you see everyday and you would not know if it was upside-down or not. A Tree, Building, Person or an Automobile for example would be important to see correctly. When you view an automobile upside-down, you recognize that this is not correct. Lets talk about the different types of telescopes and how the orientation of the image is observed through them and what you can do to correct it for land use. Refractor and Cassegrain telescopes will produce an image that is upside down when used without a diagonal. When a diagonal is used the image will be corrected right side up, but backwards from left to right. It will look like trying to read a sign in a mirror. There are special diagonals called Erect Image Prism diagonals that can correct the backwards image for land use. Newtonian Reflectors will produce an image that is upside down and are not recommended for land use. There are no ways to correct this with a Newtonian Reflector.

What are the uses of convex lenses in optical instruments?

They're caved-outward shape allows the focused object to appear backward or upside down. They also magnify various objects, which is useful for magnifying glasses and telescopes.


How do you build telescope?

To assemble your telescope, do the following:Get the two magnifying glasses and a sheet of printed paper.Hold one magnifying glass (the bigger one) between you and the paper. The image of the print will look blurry.Place the second magnifying glass between your eye and the first magnifying glass.Move the second glass forward or backward until the print comes into sharp focus. You will notice that the print appears larger and upside down.Have a friend measure the distance between the two magnifying glasses and write the distance down.Cut a slot in the cardboard tube near the front opening about an inch (2.5 cm) away. Do not cut all the way through the tube. The slot should be able to hold the large magnifying glass.Cut a second slot in the tube the same distance from the first slot as your friend wrote down. This is where the second magnifying glass will go.Place the two magnifying glasses in their slots (big one at front, little one at back) and tape them in with the duct tapeLeave about 0.5 - 1 inch (1 - 2 cm) of tube behind the small magnifying glass and cut off any excess tube remaining.Check to see that it works by looking at the printed page. You may have to play slightly to get the exact distances between the two glasses right so that the image comes to a focus


Are your eyes like a magnifying glass?

no noy rely but they r programed to c ery thin upside down


Where can you buy the glasses that flip you vision upside down in Canada?

They can be found at Spinzers.


Why do things look upside down in the microscope?

its because the lens of the microscope is convex. this means that it is curved a little bit, like the lenses of glasses. this causes the image to appear upside down. try looking into the curved part of a spoon from both sides. one side your reflection is normal, but on the other side your reflection is upside down, because of concave and convex. The side where you see your reflection normal is concave, and the side where it is backwards is convex. hope i helped!


Do leprechauns turn everything upside down?

No they don't.


Why diverging lens cannot be used as magnifying glass?

a diverging lens can not be used as a magnifying glass becuase a diverging lens( concave) lens diverges the the rays cousing the image to not be erect, but upside down. While magnifying glass ( convex) is used as it is a converging lens which focuses the rays in one point of an objects making it magnifies and erect.( right way up)


Do we see everything upside down?

No, our eyes see things right-side up, but the brain processes the images upside down before correcting them.


What happens to the printed words when viewed through the drop of water in the plastic cover?

When printed words are viewed through a drop of water on a plastic cover, refraction occurs. Refraction causes the light passing through the water drop to bend and distort the image of the printed words. This effect makes the words appear enlarged and upside-down when viewed through the water drop.


What is the custom of turning a glass upside down on the table?

Can you be more specific as to who does this?If you mean glasses already on the table when you are seated in restaurants, having them upside down keeps dust from falling into the glass and allows them to drain if they weren't QUITE dry when placed there.


Is it possible for earth to turn upside down?

yes everything is possible ( this guys stupid and probally will believe me )


When might you think you're upside down?

When your nose runs and your feet smell. Also, originally when your eyes see things, they first see it upside down, then through a process turn it into the way you see it. However, one of the reasons people might need glasses can be because the process in which the eyes turn what they originally see into what you see works differently.
