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.

Home Concept Builders Light Waves and Colors Color Filters

Color Filters

The Color Filters Concept Builder consists of 42 questions organized into 18 different Question Groups and spread across three different activities. Each activity includes six Question Groups, with questions in the same group being very similar in nature. The first activity - Light Passage - demands that learners understand what colors of light are absorbed and transmitted by various filters. The second activity - Color That Screen - challenges students to predict the light colors that reach a screen after passing through a set of two filters. The third activity - Name That Filter - requires that students predict the filter type that would cause a colored pattern to appear the way that it does when viewed through the filter. Question-specific help is provided for each of the 18 situations. The built-in score-keeping makes this Concept Builder a perfect candidate for a classroom activity.
