Objectives: After completing thismodule, you should be able to:• Define and illustrate the following terms: realand virtual images, converging and divergingmirrors, focal length, , and magnification.• Understand and apply the sign conventionsthat apply to focal lengths, image distances,image heights, and magnification.• Predict mathematically the nature, size, , andlocation of images formed by spherical mirrors.• Determine mathematically the magnificationand/or the focal length of spherical mirrors.
Analytical OpticsIn this unit, we will discuss analytical relationshipsto to describe mirror images more accurately. Butfirst we will review some graphical principlescovered in in Module 34a on light reflection.
