Chapter 4, Problem 3PL
Summary Introduction
Introduction:
Magnification is described as the capability of a lens to amplify the object. It is the degree of visual enlargement that is expressed as a ratio of the size of the image to that of an object. It is measured by the multiples of

The numerical aperture of the an objective lens:
indicates magnification
indicates the clarity
indicates light capturing ability
indicates the approprite use
Match the lens (condenser, high-dry, low-power, ocular, or oil immersion) to itsdescription. Choices may be used more than once. This objective lens provides the lowest magnification.
If you have chosen the objective lens with 10x and the ocular lens magnification is
also 10x. Then the total magnification will be 100x.
