Chapter 17.2, Problem 23SSC

To determine

The position of an object for the given specifications.

To identify: Whether the image is virtual or real.

Answer to Problem 23SSC

The object should be placed between the focal point and the mirror.

The image produced is virtual.

Explanation of Solution

Introduction:

Concave mirror is the mirror in which inner surface is acting as the reflecting surface. The light rays reflected from the concave mirror are converging and hence concave mirror is also called converging mirror. When an object is placed very close to the concave mirror the image produced will be enlarged and virtual. If the distance between the object and the mirror is increased the image size decreases and it becomes real image.

It is given that the image produced by a concave mirror is upright and large in comparision to an object. In order to get such kind of image of an object by using a concave mirror, the object should be placed in between the focal point and the mirror.

The image thus produced is virtual.
