... located at the point where the lines of the principle rays cross when they are extended (as if drawn by pencil) backwards from the paths they take beyond the lens.
And I said I wouldn't answer homework questions! ;-)

What is the role of lenses used in cameras telescopes and microscopes?
In a simple microscope, a lens magnifies the image of the sample. in a compound microscope, the objective lens magnifies the image (there may be more than one objective lens) and the eyepiece lens enlarges the virtual image (which is typically inverted by the objective lens).
Why does the lens flip and decrease the size of the picture in a camera?
The lens is convex (curved outward). Light entering the lens from the outside is refracted (bent) as it travels through it. This brings the image to a single (focal) point. The distance between the lens and the back of the camera is such that it allows a small image of the photographed scene to be visible (the picture). The image is inverted because of the refraction of light through the lens.
The inside of both camera and the eye is colored black. explain the advandage of this?
Since black absorbs light instead of reflecting it, the black finish inside of you camera stops stray light from affecting the image formed on the film or digital sensor. This stray light includes light that strikes the lens at an angle where it is not part of the image AND the light that may be reflected off of the film or sensor. The same really occurs with the inside of the eye. The sharpest image will always be produced when stray light is properly controlled.
What type of image is formed by the lens of a camera?
a upside down image is formed in your camera then flipped around when it is seen by the human eye -Monica Magallon
What kind of conversion lens would you put on your digital camera to take better pictures from far away?
A telephoto lens would bring a distant image closer.
What type of image is produced by a converging lens on the screen?
a virtual and erect image is always formed by a covering lence
What kind of image is formed by a convex lens when the object at infinity?
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.
The image produced by a convex lens depends on what?
The image depends on the distance the object is from the lens.
Name the lens that always forms virtual image?
concave lens always forms a virtual image
Why will a diverging lens never produce a real image?
A diverging lens can only produce a virtual image, because the light passing through a diverging lens never converges to a point. The virtual image produced by a diverging lens is always right-side-up and smaller than the original object. The image and the object viewed are always on the same side of the lens. Diverging lenses are used as viewfinders in cameras.
What is an upright image?
The image produced by the lens is above the principle axis.
If the image produced by a lens is the same size as the object then the lens must be?
convex lens at 2c
What is the clearest image produced by a lens?
The clearest image produced by a lens is obtained when the lens is properly focused and there is no aberration, distortion, or other optical imperfections. This results in a sharp and clear image with accurate representation of details and minimal blurriness. The clarity of the image is influenced by factors such as the quality of the lens, the aperture setting, and the distance between the lens and the object being photographed.
What is the likeness of something produced by an optical device such as lens?
image
How is the image formed by a concave lens similar to the image formed by a convex mirror?
In a concave lens the object always forms a virtual image. The convex lens also forms a virtual image.
Which type of image does a concave lens form?
Cancave lens always gives virtual, erect and diminished image.
Which lens always forms a diminished image?
concave lens formed virtual,erect and diminished image irrespective to the distance between the object and lens.
