Concave means bending inward, convex means bending outward.
Concave . . .
- thinnest in the middle
- thickest around the edge
- holds water
Convex . . .
- thinnest around the edge
- thickest in the middle
- water runs off
Any polygon that has an angle that is > 180º is a concave polygon. A convex polygon does not. e.g. All regular polygons are convex.
A non convex is a concave and a convex is differently shaped
concave
convex
A trapezoid is convex.
concave is inward, convex is outward concave is inward, convex is outward
Convex lens converges the light and a concave lens diverges the light..
the focal point of a concave mirror is positive while a convex is negative
A concave surface curves inward. Cave-in
Any polygon that has an angle that is > 180º is a concave polygon. A convex polygon does not. e.g. All regular polygons are convex.
A non convex is a concave and a convex is differently shaped
A concave polygon has lines that curve inwards whereas a convex polygon has lines that curve outwards and they are found on and inside spheres
Concave curves in (like a cave) = ) and convex curves out = (
The difference between concave and convex is that convex lenses are the type of lens that make images bigger, while concave make images smaller. Still confused, maybe this will help. When you think of concave think of a cave, how you can see a small image at the end of the cave, while convex is the opposite.
THough all are erect, in concave it will be enlarged in plane mirror of the same size as the object but in convex mirror it will be dimished
concave
Convex lens give a virtual & diminished image while concave lens give inverted virtual in rare case & magnified image.
