An image is formed in an overhead projector by shining light onto a transparent slide or transparency placed on the projector's stage. The light passes through the slide, projecting the image onto a screen or wall. The lens on the projector focuses the light to create a clear and enlarged image for viewers to see.

Is the image formed by a slide projector on the screen is magnified or diminished?
The image formed by a slide projector on the screen is typically magnified because the light rays from the projector converge before reaching the screen, which causes the image to appear larger than the actual slide.
What kind of image is formed by a slide projector?
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.
Why are the slides in a projector upside down?
The image on a projector is often upside down because of the orientation of the projector relative to the screen. Projectors are designed to be installed upside down or right-side up depending on the installation setup, and the image can be adjusted using the projector settings to correct the orientation.
Why do overhead projectors use convex lens?
Overhead projectors use convex lenses because they are designed to project and magnify an image onto a screen. The convex lens converges the light rays towards a focal point, producing a clear and focused image for the audience to see. This helps in making the projected image appear larger and sharper for better visibility.
What is the instrument used to enlarge the image of a film onto a screen?
A projector is the instrument used to enlarge the image of a film onto a screen. The film is passed through the projector, which then projects the individual frames onto a screen, creating a larger image for audiences to see.
What is the difference between a data projector and an overhead projector?
A Data Projector (referred to as Digital Projector) is a projector that gets its image from a Digital Source, such as VGA (computer), RCA (the most common A/V input), S-Video (another form of video input), and some others. These projectors are most commonly used along with DLP or LCD Technology.An Overhead Projector is an older style of projection, common in Education (Schools). These projectors are totally manual and require you to put a transparent image onto glass to project the image overhead.
What is overhead projector and projector?
An overhead projector is used to project an image of a transparency onto a wall or screen by means of an overhead mirror. There are also "slide projectors" that are used to display photographic slides on a wall or screen. A "projector" or "digital projector" would be used similar to a computer monitor or a television screen that would display an inputted image from a variety of sources (blu-ray player, computer, laptop, dvd players, game console, etc.). In the case of a projector the image is projected with the help of a light apparatus shining through a small silicon ship and projected through a lens to create an image on your wall or projector screen.
What is the name of the device that allows you to project pictures from a book?
This is referred to as an opaque overhead projector, or sometimes simply as an "opaque projector." This is in contrast to the regular overhead projector which must have transparencies to project, an opaque projector can project an image of opaque objects such as the paper pages of a book.
Is the image formed by a slide projector on the screen is magnified or diminished?
The image formed by a slide projector on the screen is typically magnified because the light rays from the projector converge before reaching the screen, which causes the image to appear larger than the actual slide.
When was overhead projector invented?
The overhead projector was invented in the 1960's.
What kind of image is formed by a slide projector?
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.
What are the dangers of using a overhead projector?
The projector can reach a pretty high temperature if left on for a while. So I think the main danger of an overhead projector is simply the heat. ;)
What is the future of the overhead projector?
My guess is that with LCD and DLP projector coming down in price, we will be seeing less and less of the overhead. When a video projector is used with an interactive whiteboard or tablet the possibilities are limitless.
What are the advantages of using presentation software?
You don't need a slide projector or an overhead projector.
A person who operates overhead projector?

Similarities of data projector and overhead projector?
The only real similarity that I can think of is they both project images onto a wall or projector screen.
