A short straight object of height \(100\, cm\) lies before the central axis of a spherical mirror whose focal length has absolute value \(| f |=40\, cm .\) The image of object produced by the mirror is of height \(25\, cm\) and has the same orientation of the object. One may conclude from the information
- A Image is real, same side of concave mirror.
- B Image is virtual, opposite side of concave mirror.
- C Image is real, same side of convex mirror.
- D Image is virtual, opposite side of convex mirror.
Answer & Solution
Correct Answer
(D) Image is virtual, opposite side of convex mirror.
Step-by-step Solution
Detailed explanation
Since orientation is same image is virtual. Since image is smaller the mirror has to be convex
