We encourage learners to solidify their learning through the use of one or more of the following resources.
The Calculator Pad, Refraction and Lenses Chapter, Problem Sets RL14 - RL20
The Calculator Pad is a powerful tool to assist you in learning to solve Physics problems. We have a collection of problems organized into problem sets according to topic and difficulty level. You solve a problem and receive immediate feedback. Many problems are accompanied by an audio-help file that provides some details regardingi the solution; other problems consists of links to appropriate tutorial pages. You can have multiple attempts on each problem, allowing you to correct your mistakes. The problem sets above are perferct follow-ups to this video.
The Physics Classroom Tutorial, Refraction and the Ray Model of Light, Lesson 5, The Mathematics of Lenses
Our written tutorial pages form the basis of most videos. So when you need a quick reference, the Tutorial page is a great place to start. This page is a great written version of the video.
