What is a real and virtual image? Can you give some examples?
I'd prefer if you gave some clear context for your question.In Physics, The real-life reflections you see in bathroom mirrors are virtual images.On the other hand, if you have ever used a camera,still or video, the image formed is a real image. Images formed in our own retinas(part of our eyes) are real images.
What are true image mirrors?
A True Mirror is made from putting two mirrors at a right angle, such that the two mirror images bounce off of each other. A True Mirror reflects your face and body in the same sense that a regular mirror does -- except that you are not reversed. The full spectrum of light is reflected, and there is 3-D depth in the image. The result is startlingly clear! If you hold your right hand out to shake it, as if you were meeting yourself on the street, the hand on your image that comes out to greet yours is the right hand! In contrast, a regular mirror will hold out your image's left hand.Try this in your home - just hold two mirrors up to each other at right angles, and you can see the effect. Of course, you'll have to ignore the large line that runs down the middle of your face, which is probably why you never paid much attention to this mirror arrangement before.
What's the translation of the phrase "True Image" into Latin?
"Imago vera" is one - for "real" it kind of depends on how you mean real. "realis" is a Latin word, but it doesn't quite have the same connotations in Classical and Medieval usage. "imago realis" though if you use it.
How exactly do I do the 90 degree mirror trick?
If the mirrors are at right angles you will see three images. Your actual head represents the fourth image. One of the images is visible in the mirror in front of you, one to your side. The final image, which is visible diagonally through the point of intersection of the mirrors, has been reflected twice. It has been swapped left to right twice. So THAT is your "true" image. Of course you can take a photo of yourself and view that. Which may be even easier.
How does a plane mirror form a real image?
It cannot.In optics, a real image is one where points on the image emit light as if the object was really there. This happens when the rays of light from a point on the object (which starts by shooting out in all directions and is hence diverging), are made to converge to a point somewhere else - whether by refracting through a lens or reflecting from a mirror. In other words, the light has to be converged.By Krishnavedala - Own work, CC0, File:Real image.svgIn the diagrams above, both the convex lens and the concave mirror act to converge the light rays coming out from the tip of the arrow. The point where they meet behaves like the tip of the original arrow - it gives off rays like it was the real thing - that’s why it’s called real.A plane mirror does not converge light. See the diagram below:Wikipedia, Public Domain, File:Plane mirror.pngThe image at A’ is not real because the real rays of light (the solid lines) don’t actually come from it. The rays diverge coming from A, and continue to diverge after reflecting off the mirror. No convergence, and hence no real image.Just in case you are wondering, the eye perceives an image nevertheless - because the brain assumes that the light is coming straight from a point - and projecting back along the dotted lines, they converge on A’ - so the brain perceives an image of A’ there. It’s a virtual image because there isn’t anything there actually emitting light. Only a perception that something is there.Thanks for asking.
Which image of a person is more real- the one we see in a camera or in a mirror?
Both a camera and mirror distort your image.A mirror image is reversed, so your facial features are “flipped.”A camera mutates your image significantly when you take pictures up-close (ie: only as far as your arm can reach). Most selfies are hugely distorted — the forehead or chin is shown much larger than it is in real life, for example.A camera can give you a more accurate view of yourself than a mirror when the picture is taken at a great enough distance. Using a friend or a tripod, you can get a pretty accurate representation of your features as they were in that millisecond.However, you are a living, breathing being (not a still object). So you move your face and body a certain way. You have a certain speaking voice. You have a personality. In person, these things are highly important to how people perceive you. I’ve often met someone for the first time after seeing them in a picture and thought, “That’s not at all what I expected!” Even when their physical features were presented pretty accurately.If you’re concerned about representing yourself accurately, be mindful of camera distortion and also imagine what certain settings, poses, facial expressions, etc., might be communicating to a stranger about who you are. Photofeeler can also help in figuring out how different photos represent you.
Splitting Multiple Images in Half?
I have about 750 pictures. What I need is an easy way to cut all of them exactly in half, and save the halves as separate files. Is there any program that can cut all of those images in half at one time? It would be a chore to do them all separately. I need them cut exactly in half and saved as separate images. And I would like to do that command to all of the images (or multiple images) at one time
True or false? Symmetry?
Correct! If the figure can be rotated and it looks exactly the same as the preimage then it is rotational symmetry. To find our the degree of symmetry divide 360 by the number of sides on the shape.
