In this lesson, we will learn how to calculate the separations between lenses used in microscopes, their powers and focal lengths, and the magnifications produced by them.

What magnification is produced?
What is the overall magnification if an 8x eyepiece (one that produces an angular magnification of 8.00) is used?
The objective and the eyepiece of a microscope have the focal lengths 3.0 cm and 10 cm respectively. Find the distance between the objective and the eyepiece that will result in a 10x magnification by the microscope.
How far behind the objective lens is the image formed by the objective lens?
What is the magnification of the image formed by the objective lens?
An eyepiece with a 2.00-cm focal length is placed 20.0 cm from the objective. How far in front of the eyepiece is the final image?
What angular magnification is produced by the eyepiece?
What is the overall magnification produced by combining the objective lens with the eyepiece?
