what is the difference between concave and convex
Answers
Answer:
concave is inside and convex is outside mirror
Explanation:
The basic difference between concave and convex are as follows:
Concave describes a shape that curves inwards. The sideview mirror of a car, which curves inwards, is a good example of a concave shape.
Convex describes a shape that curves outwards. An (American) football, which curves outwards, is a good example of a convex shape.
We most commonly use concave to describe processes linked to lenses, mirrors and reflection. A concave mirror, for example, will make you look taller due to the way light reflects back from it. Concave lenses might be used in things like telescopes, binoculars, cameras and lenses in eyeglasses. You might use concave for less scientific descriptions when describing, for example, something that curves inwards like a crater or pothole, or the stomach of a very thin person.
In some rare cases you will see concave used in a descriptive, but non-literal, sense. For example:
He lost so much weight around his face that his cheeks have taken on a hollow, concave
In the example above, concave is used in a slightly exaggerated sense, i.e. the shape we are describing might not be technically concave, but the adjective is used loosely as a synonym for thin or sunken in appearance.
Concave can be used as a noun in mathematics and geometry, i.e. it is a name for a type of shape or inwardly curved line.
