A slide projector forms an enlarged image of a transparent slide on a screen or surface by directing light through the slide onto the surface. The image will appear in color and detail, depending on the quality of the slide and projector.
A virtual image is not formed by real light rays. Instead, it appears to be located at a position where the light rays do not actually converge. This type of image is commonly seen in mirrors and lenses.
The image produced is a real image if the object is located at infinity and the lens is a convex lens. The produced image can actually be placed on a screen and photographed.
A converging lens produces a real or virtual image, depending on the object's position relative to the focal point. A real image is formed when the rays actually converge at a point, while a virtual image is formed when the rays appear to converge from behind the lens.
An inverted and real image is formed by an object placed beyond the center of curvature on the principal axis of a concave mirror. The size of the image will be smaller than the object.
A real image that can be obtained on a screen is an image formed by actual light rays converging at a point on the screen. This kind of image can be captured on a physical surface as a result of the light rays coming together. It is different from a virtual image, which is the apparent position from which the light appears to diverge after reflection or refraction.
image formed by the concave lens will be erect , virtual and smaller than the size of object.
A computer projector is a kind of an output device, used to display image on a projection screen. It receives a video signal from computer and projects an image using a lens system.Main types of computer projectors are:LCD projectors,DLP projectors,LED projectorsHybrid ( LED and Laser diode) projectors.
A virtual image is not formed by real light rays. Instead, it appears to be located at a position where the light rays do not actually converge. This type of image is commonly seen in mirrors and lenses.
A virtual erect image of the same size of the object is formed.
Anything from a carrying case, a stand for your projects, screens, mounts, pipes, cables for connecting the projector to your replacement lamps are all examples of projector accessories. Depending upon what kind of projector you have will vary what kind of accessory you will need.
The image produced is a real image if the object is located at infinity and the lens is a convex lens. The produced image can actually be placed on a screen and photographed.

A converging lens produces a real or virtual image, depending on the object's position relative to the focal point. A real image is formed when the rays actually converge at a point, while a virtual image is formed when the rays appear to converge from behind the lens.
Renting a projector can cost anywhere from about $150 to $900. It all depends on what kind of projector you want to rent and how long you expect to rent it for.
An inverted and real image is formed by an object placed beyond the center of curvature on the principal axis of a concave mirror. The size of the image will be smaller than the object.
The Optoma EP1691 WXGA DLP Projector has an integrated laser pointer.
An overhead projector is a physical device that you can use to show presentations. Some can be connected to computers and others are used to show manually created presentations made on clear plastic sheets, known as acetates. A Powerpoint presentation is a slide show that has been created using Microsoft Powerpoint. It can be on any topic and shown to an audience. Some kind of projector can be connected to a computer to show the presentation to an audience.
