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:

Options

  1. AImage is real, same side of convex mirror.
  2. BImage is virtual, opposite side of concave mirror.
  3. CImage is real, same side of concave mirror.
  4. DImage is virtual, opposite side of convex mirror.

Correct answer

D. Image is virtual, opposite side of convex mirror.

Step-by-step solution

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