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.

The L•O•S•T Art of Image Description (Converging Lenses) - Directions

Using The L•O•S•T Art of Image Description (Converging Lenses) Concept Builder is quite simple. You are shown a converging lens with its principal axis, focal point, and 2F point. An object arrow (in red) is positioned somewhere along the principal axis, either above or below the axis. You must identify the relative location and orientation of this image. You do so by tapping in a given region. The region where you tap is highlighted in red and an image arrow appears (in grey). You can change regions by simply tapping in a different region. You must also identify the relative size of the image. You do so by tapping multiple times in a region. As you tap multiple times, the image arrow toggles through each of the three options. Select the option that you are wishing for. Finally, you must decide on what type of image is formed; your choices are real or virtual. You can tap on the box in the lower left corner to toggle back and forth between virtual and real. Once you are satisfied with your answers, tap on the Check Answer button. Your answer swill be evaluated and your Progress Report will be updated.

Your goal is to earn "Stars" and to complete one or more activities. Stars are earned when you show success on a particular question. Once you show success on all the questions for a particular activity, you will earn the trophy for that activity.
