Light microscopes can magnify objects up to their size.
a. 40 x
c. 1000 x
b. 100 x
d. 50 x

The answer is C. 1000x. However an understanding of types of light microscopes is needful. A light microscope uses focused light and lenses to magnify an object. Light microscopes come in several forms. (1) Simple light microscopes use a single lens to magnify an object and cannot reach high magnification just like a handheld lens whose highest clear magnification in the best conditions is 25x. (2) Compound light microscopes use two sets of lenses - an objective lens and an eye piece. This is the type of light microscope whose magnification power reaches between 1000x and 2000x.
