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:

Image is real, same side of convex mirror.

Image is virtual, opposite side of concave mirror.

Image is real, same side of concave mirror.

Question 39 of 295

A short straight object of height $100cm$ lies before the central axis of a spherical mirror whose focal length has absolute value $\left|f\right|=40cm$ . 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:

Show answer and solution

Answer: (D) Image is virtual, opposite side of convex mirror.

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