Worksheet: The Simple Magnifier
In this worksheet, we will practice defining the angular magnification of images produced by simple magnifiers and correlating this to their focal lengths.
While outdoors on a sunny day, a student holds a large convex lens of radius 5.0 cm vertically above a sheet of paper, producing a bright spot of light on the paper 2.0 cm in radius. The magnitude of the electric field within the bright spot of light is and that of the sunlight leaving the side of the lens facing the paper is . Find the ratio of to .
