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

Diverging Lenses: Ray Diagrams and Object-Image Relations Video Tutorial
The Diverging Lens Video Tutorial discusses how diverging lenses refract light and to use such an understanding to construct a ray diagram. The L•O•S•T model is introduced to explain how to describe the image characteristics of diverging lens images. Numerous examples, illustrations, and animations assist in the explanations.
The video lesson answers the following questions:
How do you draw ray diagrams for diverging lenses?
How do you describe the image characteristics for diverging lenses?
Physics Interactive, Refraction and Lenses Chapter, Optics Bench Simulation
Sometimes you learn best by playing. And our simulations allow you to do just that. Our Optics Bench simulation allows you to move an object to varying locations in front of a lens (converging or diverging), view the light rays, and observe the image location and characteristics. Open the simulation and tap on the Diverging Lens button at the top of the simulation window to explore diverging lenses.
Minds On Physics, Refraction and Lenses Module, Mission RL10
Most students who are persistent with Minds On Physics and who rely on the Help function when having difficulty will claim that it is a game-changer. This mission pertains to the tracing of rays through a diverging lens and is a good follow up to the first several slides of this video.
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. Here's a Think Sheet that covers both ray diagrams and image characteristics for diverging lenses: Ray Diagrams for Diverging Lenses And if you need source documents (Microsoft Word), extended licensing rights, and solutions, consider the purchase of our low-cost Solutions Guide download.
Physics Interactive, Refraction and Lenses Chapter, Optics Bench Simulation
Simulations should never replace lab experiences. But there are some things that simulations can do that lab experiences can't touch ... like show principal rays approaching the lens. Our Optics Bench simulation allows a student to move an object to varying locations in front of a lens (converging or diverging), view the principal rays, and observe the image location and characteristics. Open the simulation and tap on the Diverging Lens button at the top of the simulation window to explore diverging lenses.
Minds On Physics, Refraction and Lenses Module, Mission RL10
Most students who are persistent with Minds On Physics and who rely on the Help function when having difficulty will claim that it is a game-changer. This mission pertains to the tracing of rays through a diverging lens and is a good follow up to the first several slides of this video. Like any MOP mission, they make great in-class follow-ups to coverage of concepts.
