A17-cm-long microscope has an eyepiece with a focal length of 2.7 cm and an objective with a focal length of 0.35 cm . what is the approximate magnification?

Magnification is approximately 7.71

Explanation:

Magnification is the process of enlarging the apparent size of an object. For two lenses in sequence such as in a microscope, the magnification is determined by the ratio of the focal length of the eyepiece lens to the focal length of the objective lens.

The focal length of a lens is the distance between the center of a lens and the point (focal point) where parallel rays converge after passing through the lens.

= magnification

= focal length of eyepiece lens

= focal length of objective lens
