Given f = 15 cm. Magnification = 3. So the ie v/u = 3. So v = 3u
Using lens formula, 1/f = 1/v - 1/u
Now u = -u and v = -3u and f = 15
Plug these.
1/15 = -1/3u + 1/u
Hence u = 10 cm.
The object is to be placed at a distance of 10 cm from the lens.
In a concave mirror, images can form either real or virtual, depending on the object's distance from the mirror. Real images are formed when the object is placed beyond the focal point, while virtual images are formed when the object is placed between the focal point and the mirror. The image formed is upright for concave mirrors.
Images formed by a concave lens are always virtual, upright, and reduced in size. On the other hand, images formed by a convex mirror are virtual, erect, and diminished in size. Additionally, concave lenses can form both real and virtual images depending on the object distance, while convex mirrors only produce virtual images.
A concave mirror can form both real and virtual images. Real images are formed when the reflected light rays actually converge to a point, while virtual images are formed when the reflected rays appear to diverge from a point behind the mirror. The type of image formed depends on the object distance relative to the focal point of the mirror.
When the object is placed between the focal point and the mirror in a concave mirror, an enlarged virtual image equal in size to the object is formed. In this case, the image distance is greater than the object distance, and the image is virtual, upright, and magnified.
Image formed by a concave lens or a diverging lens is virtual,upright and smaller than the object.It is used by short sighted people.

In the case of concave mirrors, the image distance is typically taken as negative when the image is formed on the same side as the object (real image). However, for virtual images formed by concave mirrors, the image distance is considered positive. For concave lenses, the image distance is always taken as negative because they always produce virtual images on the same side as the object. Therefore, while there are specific conventions, the sign of the image distance depends on the type of image and optical device being used.
Your right! You see technically we see up side down but with the light we see right side up so what that means is yes it is upside down. Well, since the brain doesn't turn it "right side up" it could be either way that you look at it.

image formed by the concave lens will be erect , virtual and smaller than the size of object.
Images formed by a concave lens are always virtual, upright, and reduced in size. The image distance is negative and the focal length is also negative. These images are formed by diverging light rays and cannot be projected onto a screen.
When a small object is placed on the principal axis of a concave mirror between the focus and the mirror, a virtual and upright image is formed behind the mirror. The image is magnified and located further away from the mirror than the object.
In a concave lens the object always forms a virtual image. The convex lens also forms a virtual image.
The image formed by a concave mirror can be real or virtual, depending on the object's position relative to the focal point. Real images are inverted and can be projected onto a screen, while virtual images are upright and cannot be projected. The size of the image can vary depending on the object's distance from the mirror.
