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

The Concave Mirror Ray Diagrams Video Tutorial demonstrates and explains how to construct ray diagrams for objects located in front of a concave mirror. Five examples are given.
The video lesson answers the following questions:
How do you draw a ray diagram for an object placed at varying locations in front of a concave mirror?
Physics Interactives: Optics Bench - Mirrors
The Physics Interactives is our simulation section. This section provides a playful way to learn. Alter a variable, experiment with a system, and interact with the simulation in order to find out how nature works. Our Optics Bench simulation allows students to explore the reflection of light by curved mirrors and the formation of images. The object location and height and the mirror focal length can be easily altered.
Minds On Physics, Reflection and Mirrors module, Mission RM5
Our Minds On Physics program provides an intense workout in careful reading, logical thinking, and conceptual reasoning. It's like eating broccoli - nobody likes it but you know it's good for you. Give Mission RM5 on Ray Tracing a try. It's great nutrition for your Physics brain. Use the Help link for question-specific help.

Tutorial on Reflection and the Ray Model of Light, Lesson 3
When you need to quickly review a topic and/or freshen up on a concept, The Tutorial section of our website is your go-to place. Many teachers include these as links for students on their course management sites. The page titled Ray Diagrams for Concave Mirrors makes a good complement of this video.

Teacher Toolkits: Image Formation by Curved Mirrors
We love our Teacher Toolkits. We hope you do as well. They include a collection of links to vetted resources throughout the web that are standards-based and multi-media driven.
