Question
A short straight object of height 100 cm 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 25 cm and has the same orientation of the object. One may conclude from the information :
Select the correct option:
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.
✓ Correct! Well done.
✗ Incorrect. Try again or view the solution.
Solution
Since orientation is same image is virtual. Since image is smaller the mirror has to be convex Ans. (4)
