## What is difference between convex and concave?

Concave describes shapes that curve inward, like an hourglass. Convex describes shapes that curve outward, like a football (or a rugby ball).

## Which is concave side?

Concave describes an inward curve; its opposite, convex, describes a curve that bulges outward. They are used to describe gentle, subtle curves, like the kinds found in mirrors or lenses. If you want to describe a bowl, you might say there is a large blue spot on the center of the concave side.

## What are the 3 main differences between a convex and concave mirror?

Concave mirror | Convex mirror |
---|---|

It is also called a converging mirror. | It is also called a diverging mirror. |

It has a real focus. | It has a virtual focus. |

The magnification of a concave mirror can be greater, equal or less than 1. | The magnification of a convex mirror is always less than 1. |

## What is concave mirror with example?

Concave mirror v/s convex mirror – result

Concave mirror | Convex Mirror |
---|---|

The examples of concave mirrors are the mirrors used in automobile head lights, reflecting telescopes, torch lights, etc. | The examples of convex mirrors are the mirrors used as rear side mirrors of vehicles, optical instruments, calling bell, etc. |

## What are the similarities between concave and convex mirrors?

A convex lens acts a lot like a concave mirror. Both converge parallel rays to a focal point, have positive focal lengths, and form images with similar characteristics. A concave lens acts a lot like a convex mirror.

## What shape is a concave?

Concave shapes are those shapes in which at least two sides are pushed inwards. Can you think of any space object that is concave in shape? A star is a concave shape.

## What is a convex curve called?

A parabola, a simple example of a convex curve.

## What are concave examples?

Unlike plain mirrors, spoons have curved surfaces. The front side of a spoon is curved inwards. Such a surface is called concave. The inside part of a bowl is also an example of a concave surface.

## What are some examples of concave?

Some examples are binoculars, telescopes, eyeglasses, cameras, flashlights and lasers….Explanation:

- Binoculars and telescopes.
- Eye Glasses to correct nearsightedness.
- Cameras.
- Flashlights.
- Lasers (CD, DVD players for example).

## What is a convex and concave mirror?

A curved mirror is a mirror with a curved reflecting surface. The surface may be either convex (bulging outward) or concave (recessed inward). Most curved mirrors have surfaces that are shaped like part of a sphere, but other shapes are sometimes used in optical devices.

## What are convex and concave mirror?

## What does convex mean in math?

Convex, meaning “curving out” or “extending outward” (compare concave), may refer to: Convex Computer , a company that produced a number of vector supercomputers. Convex function, in mathematics. Convex lens, in optics. Convex polygon, a polygon in which no line segment between two points on the boundary ever goes outside the polygon.

## Which side is convex?

In geometry, a convex curve is a simple curve in the Euclidean plane which lies completely on one side of each and every one of its tangent lines. The boundary of a convex set is always a convex curve.

## What is an example of a convex shape?

The definition of convex is curving outwards like the edge of a circle. An example of convex is the shape of the lens in eyeglasses.

## What are concave shapes?

concave shape – a shape that curves or bends inward. concavity, incurvation, incurvature. solid – a three-dimensional shape. dome – a concave shape whose distinguishing characteristic is that the concavity faces downward.
