Chapter 13, Problem 1STP

To determine

To choose: The correct option.

Answer to Problem 1STP

The correct option is (B).

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.

When an object is placed at focal point of a concave lens its image is formed at infinite since the resultant ray are goes parallel to the optical axis, but when the object is placed at less than the focal length the object is form at finite distance and it became upright and enlarge. Therefore correct option is B.

Conclusion:

Hence, the correct answer is (B).
