Convex (converging) lenses can form either real or virtual images (cases 1 and 2, respectively), whereas concave (diverging) lenses can form only virtual images (always case 3).

A virtual image is produced with the help of a diverging lens or a convex mirror. A virtual image is found by tracing real rays that emerge from an optical device backwards to perceived or apparent origins of ray divergences.

Bottom: The formation of a virtual image using a convex mirror. In both diagrams, f is the focal point, O is the object, and I is the virtual image, shown in grey. Solid blue lines indicate (real) light rays and dashed blue lines indicate backward extension of the real rays.

In this section we deal with a convex lens and its ability to form virtual images. Virtual images are ones that cannot be formed onto a screen. We see the image at a place where no light rays are converged. They appear to be coming from that place, but they really aren't.

A magnifying glass is a convex lens used to make an object appear much larger than it actually is. This works when the object is placed at a distance less than the focal length.

A real image can be displayed on a screen or piece of paper or on a wall, whereas a virtual image cannot. A virtual image can be seen with the eyes but it's impossible to display the image on a screen.

Dec 16, 2024 · If image is above the principal axis, image height will be positive. It means that image is erect. If image is below the principal axis, image height will be negative. It means that image is inverted.

Convex lenses, which are thicker in the middle than at the edges, converge light rays to a focal point, enabling them to form both real and virtual images. Our simulator vividly illustrates the working of this optical tool, allowing you to explore the intricacies of convex lens.

Objects within a focal length of a convex lens produce upright, magnified virtual images, whereas concave lenses produce upright and diminished virtual images. Convex lenses correct long-sight by shortening the focus, and concave lenses correct short-sight by lengthening the focus.

Oct 8, 2024 · What is a virtual image in a convex lens? A virtual image is formed when light rays diverge after passing through a convex lens, appearing to converge on the same side as the …
