Physics Classroom is making strides to make our site accessible to everyone.
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.
The Primary Navigation handles the first 2 levels of site pages.
The Secondary (which is not always available) handles the 3rd and 4th level of structure.
The Page level navigation allows you to navigate the current page's headings quickly.
The Header Navigation contains the Light/Dark Mode toggle, Search, Notifications and account login.
The Breadcrumb Navigation contains the breadcrumb of the current page. If the current page has a breadcrumb, you can get to it by skipping to the content and tabbing in reverse (shift plus tab).
The Footer Navigation contains links such as Privacy, Contact, about and terms.
Some resources contain an Audio Player that can be activated by holding down the T key for 3 seconds, and then using K to pause and resume.
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 this link to contact us.
Any ray of incident light that passes through the focal point and strikes a concave mirror will reflect and _____.
Concave Mirrors - Rules of Reflection Light reflects off any surface - plane mirror, curved mirror, or non-mirror - according to the law of reflection. For concave mirrors, some generalizations can be made to simplify ray construction. They are:
An incident ray traveling parallel to the principal axis will reflect and pass through the focal point.
An incident ray traveling through the focal point will reflect and travel parallel to the principal axis.
An incident ray traveling through the center of curvature will reflect and travel back along the same path from which it came.
