focal power

magnifying power
linear magnification
Solution
The converging or diverging ability of a lens or mirror is referred to as its "focal power." Focal power, measured in diopters (D), is the reciprocal of the focal length (in meters). It indicates how strongly the lens or mirror converges (positive focal power) or diverges (negative focal power) light.
