Chapter 13, Problem 13STP

To determine

To Find: The object distance of the image from the lens at which the object distance is equal to image distance.

Answer to Problem 13STP

Theobject distance should be $10\text{cm}$ .

Explanation of Solution

Introduction:

A curved mirror is a mirror with a curved surface which reflects. The surface can be convex or concave. Many curved mirrors have surfaces shaped like part of a sphere but often other shapes are used in optical devices.

Given:

  

From the given figure it is seen that as the object distance is varies image distance is also varies. From the graph if the object distance is $10\text{cm}$ then image distance is $10\text{cm}$ . I.e. at object distance $10\text{cm}$ the object distance is equal to image distance.

Conclusion:

Hence, the object distance should be $10\text{cm}$ .
