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 Refraction and Lenses Law Enforcement: Refraction Directions

Law Enforcement: Refraction - Directions

Using the Refraction - Law Enforcement Concept Builder is quite simple. There are four activities. As you progress through any of the activities, you will be presented with a question that you will have to answer. The question presents three situations involving the refraction of light at the boundary between two media. The first three activities focus on a single variable. The three variables are the relative speed of light of the two media, the relative optical density of the two media, and the relative index of refraction of the two media. The fourth activity includes all three variables mixed together.

In each situation, you will have to determine which of the three situtations violate the law of refraction regarding the direction that light bends. Tap on any situation that does. Once you tap on one or more situations, they will be displayed behind bars (since they break the law of refraction) and a Check Answer button appears. Once you are satisfied with your answer, tap on the Check Answer button. Your answer will 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 demonstrate success with a particular Question Group. Once you show success on all the Question Groups of a particular activitiy, you will earn the reward for that activity.
