Physics Classroom is making strides to make our site accessible to
everyone, and features many accessibility features.
Our site contains 6 navigation areas. The Primary, Secondary,
and Page Level navigations have a screen reader version of their nav
structure that allows using the left and right keys to navigate sibling
navigation items, and up or down keys to navigate parent or child
navigation items. The others can be navigated using tabs.
Within the main content, we leverage headers to provide in page or
in tool navigation.
Although we are still rebuilding our content to leverage these tools,
our images should have both short and verbose descriptions, the later
describing in great detail the image for those who cannot see. Any
formulas found within the images are often in the image figure below the image.
Equations and formulas are rendered using MathJax, which has both verbal,
braille (including nemath braille), and keyboard navigation within them.
Learn how to configure and leverage this for various screen readers on our
Equation Navigation Page.
While not every area of
Physics Classroom is usable purely from keyboard and screen reader, we
are committed to continue work on making this possible. If you have
questions or need additional help, please use

Determining the Index of Refraction Video Tutorial
The Determining the Index of Refraction Video Tutorial utilizes four example problems to demonstrate how to use Snell's Law to determine the index of refraction value of an unknown material. Most of the examples center around lab-like scenarios.
The video lesson answers the following questions:
How do you analyze the path of light through a material in order to determine the index of refraction value of the material?
Calculator Pad, Refraction and Lenses Chapter, Problem Sets RL4 - RL9
If you need guided practice and help with using Snell's Law to solve Physics word problems, then you likely going to have difficulty finding a better resource than our Calculator Pad problem sets. Each problem is accompanied by a set of helpful resources that provide guidance on how to approach the problem. Problem Sets RL4 through RL9 have consist of many practice problems. Pick the ones you want to attempt and learn.
Minds On Physics, Refraction and Lenses Module, Mission RL4
Student persistence with Minds On Physics, combined with reflective thinking and the use of our Help function, will put any student at the top of the class. This mission pertains to the use of Snell's Law equation. Take the challenge.
Curriculum Corner, Refraction and Lenses
Our Curriculum Corner section of the website includes a large collection of Think Sheets that make great complements to the video. Each Think Sheet focuses on a single concept and is structured to incrementally guide a student through the concept. They make for great follow-ups to the video, good cooperative group activities, and inclusions in any lesson plan. And if you need source documents (Microsoft Words), extended licensing rights, and solutions, consider the purchase of our low-cost Solutions Guide download. Here's a Think Sheet that fits the video quite well: Snell's Law
Calculator Pad, Refraction and Lenses Chapter, Problem Sets RL4 - RL9
If you are looking for guided practice for your students as they use Snell's Law to solve Physics word problems, then you likely going to have difficulty finding a better resource than our Calculator Pad problem sets. Each problem is accompanied by a set of helpful resources that provide guidance on how to approach the problem. Problem Sets RL4 through RL9 have consist of many practice problems of varying degree of difficulty. Numerical information is randomly generated; answers are instantly evaluated; multiple opportunities are provided to get the answers correct.

Physics Interactives, Refraction and Lenses Section, Refraction
Our refraction simulation provides a great environment for students to explore what happens when light reaches the boundary between two materials. Combine the simulation with the use of one of our student activity sheets and the accompanying Concept Checker and you will have the start of a great lesson plan.
Physics Interactives, Refraction and Lenses Section, Least Time Principle
Our Least Time Principle simulation centers around the classic questiion of what path does the light guard take to reach the drowning swimmer in the least amount of time? Students use a trial and error method to determine the optimal entry point - the point that takes the least amount of time. Once found, the angle of approach and departure from the boundary and reported. Students then relate the angles to the running and the walking speed of the life guard. This is a great inquiry-driven activity.
Concept Builders, Reflection and Refraction Chapter: Law Enforcement - Refraction
Concept Builders will help do what it's name boasts of - build a concept. This Concept Builder may be a student's best next step after the video. They must use information about relative speed, optical density and n value to identify any diagram that displays the wrong direction of bending. They're going to have to think ... and not too many of use Ts will complain about that.
