This interactive tutorial explores how moving the object farther away from the center of curvature affects the size of the real image formed by the mirror.

What AreFresnellenses used for

Concave mirrors have a curved surface with a center of curvature equidistant from every point on the mirror's surface. An object beyond the center of curvature forms a real and inverted image between the focal point and the center of curvature.

To operate the tutorial, use the Object Position slider to translate the arrow back and forth in front of the mirror. As the arrow is moved away from the mirror, the inverted, real image grows larger and becomes equal in size to the object at the center of curvature. As the object is moved beyond the center of curvature, the image continues to grow smaller. When the object reaches the focal point, an upright, virtual image is produced on the rear side of the mirror and decreases in size as the object approaches the mirror surface.

Fresnel lenses are still in operation today. According to the US Lighthouse Society, more than 75 Fresnel lenses are in use in American lighthouses, and businesses such as Dan Spinella’s Artworks Florida craft replicas that capture the beauty — and functionality — of the 19th-century breakthrough.

As the above video shows, these lenses satisfied a need for lighthouses that could shine farther and through dense layers of fog. The Fresnel lens, invented by Augustin-Jean Fresnel, helped do that by capturing all the light coming from a lamp, then magnifying and steering it in one direction. Suddenly, lighthouses became more useful and shipwrecks diminished.

Our mission could not be more clear and more necessary: We have a duty to explain what just happened, and why, and what it means for you. We need clear-eyed journalism that helps you understand what really matters. Reporting that brings clarity in increasingly chaotic times. Reporting that is driven by truth, not by what people in power want you to believe.

The distance from the reflecting surface to the focal point is known as the mirror's focal length. The size of the image depends upon the distance of the object from the mirror and its position with respect to the mirror surface.
