Find the Focal Length JS Model 

written by Andrew Duffy and Mario Belloni

The Find the Focal Length JavaScript Model shows how a spherical mirror reflects the rays from a point source.  The Model specifically asks the user to determine the focal length of the mirror. There are at least 4 different ways to find f.

The Find the Focal Length JavaScript Model was developed using the Easy Java/JavaScript Simulations (EjsS) modeling tool. You can modify this simulation if you have Easy Java/JavaScript Simulations (EjsS) version 5.2 or above installed by downloading and importing the zip file into EjsS.
