Suppose a lens of power -2.25 D (such as is used to correct myopia) is held 22.5 cm away from an object. What magnification will be produced by the lens?
What magnification will be produced by a lens of power –4.00 D (such as might be used to correct myopia) if an object is held 35 cm away? Your answer should be a number with two decimal places. Hint: you need to first determine the focal distance of the lens.
