Question
A beam of light parallel to the principal axis of a convex mirror appears to diverge from a single point after reflection, at a distance of 56 cm from the pole of the mirror. The focal length of the mirror is ____ cm.
Hint:
56
The correct answer is: 56
the distance between the focus and the pole of the mirror is called focal length.
