Question

Magnification produced by a concave mirror is always:

Answer 1

In this question, first we will see the basic definition of a mirror and then we will study about the concave mirror. This will help us to get the required answer to our question. Further, we will see the basics of the lens and its types. We will also know about the applications of a concave mirror.

Complete answer:
As we know a mirror is defined as a device that contains a surface, which is mainly used to reflect light. As mirrors do not usually absorb much light, most of the light is redirected. The mirror and the object's overall quality is generally preserved in the new image.
In the given figure, the shaded portion is not used to reflect light.

Concave mirror.

As we know that a concave mirror can create real as well as virtual images depending upon the position of the object. The size of the image also varies depending upon the position of the object, sometimes smaller or larger than the size of object. So, we can say that the magnification produced by a concave mirror is less than one or more than one which depends upon the position of the object .

Note:
We should remember that a mirror will have only one focal point, which is in front of the mirror. We should note that compound lenses are constructed from a combination of different simple lenses. The lens which is used to build a compound lens may have different refractive indices and other properties.
