- 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.

A concave mirror has silvering on the interior surface (think “cave”), and a convex mirror has silvering on the exterior surface. Consider rays that are parallel to the optical axis of a parabolic mirror, as shown in Figure \(\PageIndex{2a}\).
Jul 20, 2017 · In English, there is a great trick from David MacKay's recommended book on information theory: Just keep pronouncing the word "convex" as "convec-smile" and "concave" as "conca-frown" and the direction of the mouth of the corresponding smiley will tell you what the graph of the function looks like.
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.
Basically, the reflecting surface of the convex mirror bulges outside while the concave mirror bulges inwards. The major difference is the image that forms in these two mirrors. In other words, diminished images form in convex mirrors while enlarged images form in concave mirrors.

f is + if the mirror is a concave mirror; f is - if the mirror is a convex mirror; d i is + if the image is a real image and located on the object's side of the mirror. d i is - if the image is a virtual image and located behind the mirror. h i is + if the image is an upright image (and therefore, also virtual)
