Physics - Geometrical Optics Question with Solution | TestHub

A short straight object of height$100 \mathrm{cm}$lies before the central axis of a spherical mirror whose focal length has absolute value$\left|f\right|=40 \mathrm{cm}$. The image of object produced by the mirror is of height$25 \mathrm{cm}$and has the same orientation of the object. One may conclude from the information:
