Chapter 31: Problem 3

Under what circumstances will the image in a concave mirror be the same size as the object?

Short Answer

Expert verified
The image in a concave mirror will be the same size as the object when the object is placed at the center of curvature of the mirror.

Step by step solution

01

Understanding Concave Mirrors

A concave mirror, also referred to as a converging mirror, is a mirror that has reflecting surface which bulges inward. The formation of images in a concave mirror is dependent upon how far the object is from the mirror.
02

Relating Object Distance to Image Size

In a concave mirror, the size of the image is the same as the object when the object is placed at the center of curvature of the mirror. The center of curvature (C) is the point located on the center of the sphere from which the mirror was cut.
03

Forming Image at the Center of Curvature

The image will form directly at the center of curvature if the object is placed there. The image would be inverted and the same size as the object.
