C)11
D)3.5

Question

Quizplus · Accepted Answer

The maximum magnification of a magnifying lens can be found using the formula:
magnification = 1 + (focal length / distance of near point)
Plugging in the given values, we get:
magnification = 1 + (10 cm / 25 cm)
magnification = 1.4
Therefore, the maximum magnification is 1.4, which is closest to option D (3.5) but not exactly the same. So none of the given options are correct.
