Can real images be projected on a screen?
Yes, real images can be projected on a screen by using an image projector that magnifies and projects light through a lens onto the screen. This allows the image to be displayed in a larger format for viewing by an audience.
What lenses only produce a virtual image because the light rays never converge?
A diverging lens, also known as a concave lens, only produces a virtual image because the light rays that pass through it diverge away from each other. This causes the rays to appear as if they are coming from a point behind the lens, creating a virtual image that cannot be projected onto a screen.
When an object is placed near a screen why is there no image formed?
This is due to the way that light rays bend. When the image is close to the screen, the light rays reflect off the mirror and do not converge or diverge. Rather than travel perpendicular to each other, the light rays travel parallel?æto each other. This does not allow an image to form.
What does actual pixels mean?
"Actual pixels" refers to viewing an image on a screen at a 1:1 ratio, where each pixel in the image corresponds directly to a pixel on the screen. This allows you to see the image in its true size and resolution without any scaling or interpolation.
How do coloured filters work in 3D glasses?
Three dimensional (3D) effects are seen when the left eye and right eye view a scene from slightly different angles. The brain can be fooled into seeing the same if each eye is shown a slightly different image. The two images are projected on a screen in complementary colours. Glasses with matching filters ensure that each eye only sees one image. Complementary pairs of colours include red and green, red and blue, blue and green, red and cyan, green and magenta or blue and yellow.
How can a real image be distinguished from a virtual image and can each type of image be projected on screen?
If an image can be formed on screen it is classified as real. Virtual images cannot be projected on an image.

Is there a need to calibrate big screen TV?
It depends on the type of big screen. Large plasma or LCD displays need no calibration although there are some set up procedures in most that will help to optimise the image when it is installed. Projected television displays may need an amount of calibration. The latest rear projected televisions use LCD or DLP technology and these will require nothing more than a focus adjustment. Even that adjustment is not available on many models. Older projectors use three CRTs (vacuum tubes similar to older televisions). These televisions need to be set up to produce a square image positioned properly on the screen and then the red and blue images need to be aligned to the green image. It's a process that can take several minutes to an hour or more. Once done, the image tends to remain stable unless the television is moved. As the television ages, it will normally benefit from another set up that will improve the image quality. Each model has a similar set up process but the manual will provide full and detailed instructions.
How does the Nintendo 3DS's 3D screen work?
The Nintendo 3DS produces the illusion of 3D using autostereoscopy. You can imagine the screen as showing two images at once, and having another screen (the parallax barrier) over it to only allow each eye to see one screen. Basically, the screen works by forcing each eye into seeing a different image. The screen has two images; each image is a different perspective of the same image, as if you were actually looking at a real object in real life. In real life, your eyes both see a slightly different perspective of the same object(s), and that provides the 3D effect, as abjects closer to you will have a bigger difference in the perspective. The same goes with the 3DS: it forces each eye into seeing a different perspective. and as a result, your eyes are tricked into seeing objects on the screen just as you see 3D objects in real life. It's all about making your left eye see the left side of the object, and your right eye seeing the right. That's what creates the illusion of depth. If that's too confusing: it's magic. It's a magic screen.
How is the visual pathway from the eyes different from that of the ears or hands?
each eye is not primarily connected to one hemisphere only instead, each visual half field is projected to the opposite hemisphere so, if an image is seen in the right visual field it would be seen in the left hemisphere and if an image is seen in the left visual field it would be seen in the right hemisphere
Witch one is good LCD projected or DLP projected?
They're both `good', but it's your personal choice that matters. Each had its good points and each have their drawbacks from a technical point of view.
What are the steps involved in T Shirt screen printing?
First, the image is separated into up to 4 colors. Then each color is printed on a piece of clear plastic in black. Then the sheet of plastic is taped to a printing screen which has a light-sensitive gel on it, and exposed to light. Then the screen is washed, and only the area where the image was can pass paint through. Then the screen is attached to a printing press where shirts are run through, and each color is added to the shirt. Then the shirt is run through a dryer (like a pizza oven) on a conveyor belt, and folded.
