- An easy way to test for both is to connect two points on the curve with a straight line. If the line is above the curve, the graph is convex. If the line is below the curve, the graph is concave.

The method for drawing ray diagrams for concave mirror is described below. The method is applied to the task of drawing a ray diagram for an object located beyond the center of curvature (C)of a concave mirror. Yet the same method works for drawing a ray diagram for any object location. 1. Pick a point on the top of the object and draw two incident...
A ray diagram for the case in which the object is located in front of the focal point is shown in the diagram at the right. Observe that in this case the light rays diverge after reflecting off the mirror. When light rays diverge after reflection, a virtual image is formed. As was done with plane mirrors, the image location can be found by tracing ...
Thus far we have seen via ray diagrams that a real image is produced when an object is located more than one focal length from a concave mirror; and a virtual image is formed when an object is located less than one focal length from a concave mirror (i.e., in front of F). But what happens when the object is located at F? That is, what type of image...
Aug 16, 2021 · Figure 11.7.3: Parallel rays of light reflected from a convex spherical mirror (small in size compared with its radius of curvature) seem to originate from a well-defined focal point at the focal distance f behind the mirror. Convex mirrors diverge light rays and, thus, have a negative focal length.
Sep 9, 2023 · Ways to Remember. Concave: Think “Con-cave”; it has a “cave” or an inward dip. Convex: Think of “Con-vex” as “convicts” trying to escape, bulging outwards. Concave and Convex Lenses. Concave lenses focus light inside the curve of the lens, while convex lenses focus light using the outer curve.
Oct 1, 2023 · If an object is placed further from the lens than the focal length f then a real image will be formed, and the converging lens ray diagram will be drawn in the following way: Diagram showing the formation of a real image by a lens.
Jan 26, 2023 · focal lengths of concave mirrors are positive, \(f>0\). focal lengths of a convex mirrors are negative, \(f<0\). image distances for real images are positive, \(i>0\).
