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 RM8 Convex Mirror Ray Tracing

The Question

An image is a likeness of an object which is at a location where ______.

Define Help

Definition of Image:
An image is a likeness of an object which is at a location in space where it would seem to all observers as though the reflected light is coming from.

Think About It

Suppose you place a small light bulb in front of a large convex mirror. Light rays extend from the bulb in all directions, many of which will approach the convex mirror. We refer to these rays as incident rays. Each incident ray reflects off the convex mirror according to the law of reflection. The reflected rays diverge upon reflection from the convex mirror. It is because of these reflected rays of light that an observer can view the image of the light bulb when looking in the mirror. If each of these diverging reflected rays could be extended backwards from the eye of the observer toward the convex mirror, they would all intersect at the same location. This intersection point would be behind the convex mirror. It is the image location. The image location is the location in space where it would seem to all the observers as though the reflected light is coming from.
