A concave curve is a curve with negative second derivative. f''(x)<0.
Because the light can come in at all different angles. When the light comes in, it will all meet in the middle.
Convex is used for looking closer at.
The convex mirror curves outwards while the concave mirror would curve inwards. The convex mirror traces light out making faraway objects bigger like in a telescope.
concave and convex refer to the curve of the mirror. if it is concave, it curves in at the middle, like a 'cave'. if it is convex, it curves out at the middle, like an eye. think of a spoon - one side is convex, the other is concave. this curve will affect the image the mirror shows.
concave (bulges inward) convex (bulges outward)
A convex mirror has the same type of curve as the bottom of a spoon - it bulges out. Mirrors reflect.
They are: concave (curved away from the observer) convex (curved toward the observer)
The opposite of convex is concave. Concave shapes have an inward curve, while convex shapes have an outward curve.
Convex lenses protrude or curve out, concave lenses curve in, like a cave...
Convex lens curve outwards.
Convex lenses makes an object appear larger and closer. They curve inwards toward the center.
A convex curve in the shaft of a column
An open curve, perhaps.
yes
The convex mirror curves outwards while the concave mirror would curve inwards. The convex mirror traces light out making faraway objects bigger like in a telescope.
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
The amount of curve (convex) in the lens determines the strength of the lens, thereby determining the effectiveness (or strength) of the lens. This is how the prescription strength of contact lenses is determined.
concave and convex refer to the curve of the mirror. if it is concave, it curves in at the middle, like a 'cave'. if it is convex, it curves out at the middle, like an eye. think of a spoon - one side is convex, the other is concave. this curve will affect the image the mirror shows.
