Question

It is observed that when an object is placed in front of a spherical mirror, a real and magnified image is formed. The type of mirror used and the position of the object are, respectively,

• A. Concave, between pole and focus
• B. Concave, beyond centre of curvature
• C. Concave, between centre of curvature and focus
• D. Convex, at $20\text{cm}$ from the pole

Answer 1

The correct option is C Concave, between centre of curvature and focus

It is give that image formed is real, i.e., it must be inverted. Hence, the mirror used is concave.

As the image is magnified, the object is placed between centre of curvature and focus. The magnified and real image is formed beyond the centre of curvature, as we can see in the ray diagram.



Hence, $\left(C\right)$ is the correct answer.
