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 RM1 Law of Reflection

The Question

The diagram depicts light reflecting off a planar surface. If angle A is a 25 degree angle, then the angle of reflection is ____ degrees.

Physics Rules

The Law of Reflection:
When a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection. The incident ray and reflected ray are always located within the same plane.

Define Help

Definition of Angle of Incidence:
The angle of incidence is the angle made by the ray of light approaching a surface (incident ray) and the normal line drawn to the surface at the location where the ray contacts the surface.
 

Definition of Angle of Reflection:
The angle of reflection is the angle made by the ray of light leaving a surface (reflected ray) and the normal line drawn to the surface at the location where the ray leaves from the surface.
