What is the minimum number of rays required for locating the image formed by a concave mirror for an object? Draw a ray diagram to show the formation of a virtual image by a concave mirror.
(N/A) To locate the image of an object formed by a concave mirror,a minimum of two rays are required.
Ray diagram: $A$ concave mirror forms a virtual,erect,and magnified image of an object when it is placed between the focus $(F)$ and the pole $(P)$ of the mirror. The rays appear to diverge from behind the mirror,forming a virtual image as shown in the diagram.
