Question

A short straight object of height $100cm$ lies before the central axis of a spherical mirror whose focal length has absolute value $|f|=40cm.$ The image of object produced by the mirror is of height $25cm$ 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 1

Answer: (D)

Since orientation is same image is virtual. Since image is smaller the mirror has to be convex
