A virtual image is formed where light rays appear to converge but do not actually intersect. It cannot be projected onto a screen and is always upright.

No, flat mirrors produce virtual images. The image appears to be behind the mirror and is not a true representation of the object's size or distance from the mirror.
False. A convex lens will produce a smaller, upright, and virtual image if the object is placed inside the focal point.
A virtual image is always upright in relation to the object.
A convex lens can produce a real image when the object is beyond the focal point and the light rays converge at a point to form an image. It can also produce a virtual image when the object is placed within the focal point and the diverging light rays appear to come from a point behind the lens.
A negative sign is associated with a virtual image because the light rays do not actually converge at the location of the virtual image. Instead, they appear to diverge from a point behind the mirror or lens, creating the virtual image. Mathematically, this distance is represented as negative to indicate the direction of the virtual image.
