Detailed explanation-1: -The image is formed at the distance of 54.54 cm behind the mirror and is virtual and erect.
Detailed explanation-2: -Convex mirrors always form virtual images.
Detailed explanation-3: -As shown above, real images are produced when the object is located a distance greater than one focal length from the mirror. A virtual image is formed if the object is located less than one focal length from the concave mirror.
Detailed explanation-4: -A concave mirror of focal length 1.5m forms an image of an object placed at a distance of 40cm. Find the position and nature of the image. ⇒ v = 0.5454m = 54.54cm (1m = 100 cm). Since v = 54.54cm which is positive hence image is behind the mirror.
Detailed explanation-5: -An object is placed at a distance of 1.5 m from a screen and a convex lens is interposed between them. The magnification produced is 4.
