Assignment

Construct a telescope using the given parts, and determine the zoom factor graphically!

Note for the teacher

In order for this exercise to make sense, you want to show merely the needed parts for the telescope (two convex lenses and a parallel light source). In order to do this and to set up the initial conditions for this exercise, the following JavaScript code is executed upon loading of this web page:

function initialize() {
     simulation.jsSetVisible("no","PointSourceButton")
     simulation.jsSetVisible("no","ParallelSourceButton")
     simulation.jsSetVisible("no","LensButton")
     simulation.jsSetVisible("no","ObjectButton")
     simulation.jsSetVisible("no","IrisButton")
     simulation.jsSetVisible("no","DeleteButton")
     simulation.jsSetVisible("no","PropertiesBox")
     simulation.jsAddParallelSource(50);
     simulation.jsAddLens(150, 100);
     simulation.jsAddLens(350, 60);
}
