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.

Mission RL3 Optical Density, n, and Refraction

The Question

Materials that are most optically dense will have a _____ index of refraction value; light will move ____ through these materials.

Physics Rules

Optical Density and the Speed of Light:
The speed at which light travels through a medium is dependent upon the optical density of that medium. Light travels fastest in media that are least optically dense.

Physics Rules

Optical Density and the Index of Refraction:
Every material is identified by a unique index of refraction value. The index of refraction value is an experimentally determined value that provides a relative measure of the optical density of that material. The higher the index of refraction value, the more optically dense a material is.

Think About It

In this question, you have to relate two ideas. The ideas are expressed in the two Know the Law sections. Some careful reading and some logical thinking will have you on your next question in no time.
