Question

The image formed by a spherical mirrors virtual. The mirror is

• A. Convex
• B. Concave
• C. Either convex or concave
• D. Cannot say

Answer 1

The correct option is C

Either convex or concave

To form a virtual image, we may use Either convex or concave mirror

Convex mirror

1. The image formed by the convex mirror is always virtual and upright. Placing the
2. object at infinity creates a focused virtual image and reduces the size of the image.
3. When a ray is directed towards the principal focus of a convex mirror, after reflecting it will emerge parallel to the principal axis.

Concave mirror

1. Curved mirrors create a virtual image only if the object is placed between F and P.
2. This image will always be larger than the object
