The Optics Equation is the most important equation in the study of geometrical optics. In this new Windows application, students can enter any value for the distance to the object (p), the distance to the image (q), and the focal length (f), when they practice the optics equation. After finding the desired value, this application will determine if the image involved is real or virtual, if it is erect or upside down, and if it is enlarged or reduced in size. In addition, it will indicate what type of lens or mirror it should be, and what case it is. A good thing is that students can practice unlimited sets of different values, and the application always will display the results, whatever the case it is.

The way this application was designed, it will make possible for students to master the understanding of geometrical optics in a shorter period of time.

It takes just one minute learning to use this tutorial. Simply place the Optics Equation - Geometrical Optics file in any folder or subfolder you want. To open it, simply double click it with your mouse, and the students will be ready to start enjoying this activity. If you have any questions, we will be happy to answer them as soon as possible. Again, this program is for computers using Windows 10 or newer.
