no image forms

Detailed explanation-1: -When an object is placed in front of a concave mirror of focal length f, a virtual image is produced with a magnification of 2. To obtain a real image with a magnification of 2, the object has to be moved by a distance equal to. No worries!
Detailed explanation-2: -The correct answer is a. virtual, erect, and the magnification is greater than one. The center of a concave mirror is also called its vertex. When an object is placed between the center of the mirror and the focus then a virtual and erect image is formed.
Detailed explanation-3: -When the object is located at the focal point, no image is formed. As discussed earlier in Lesson 3, light rays from the same point on the object will reflect off the mirror and neither converge nor diverge.
