The basic difference between concave and convex is that Concave refers to that curve or surface that resembles the inner part of a surface, that is, it presents a sunken part directed towards the observer. Convex is that curve or surface that presents a curve directed towards the observer.
In geometry, concave refers to that curve or surface that resembles the inner part of the circumference or a sphere, this means that it presents a sunken part directed to the observer.
This term is used in mathematics and physics to refer to a type of angle that is generated before a curve, that is, where the internal cavity is generated.
This term also applies to mirrors. A concave mirror is one that has an inward curvature and that has certain utilities. They are used in telescopes and in those instruments used to see long distances.

It is an adjective used in mathematics and physics to describe something whose appearance is similar to the external face of a circle or sphere.
For economics, the term convexity represents a considerable resource for measuring the risk of an interest rate and is used to calculate at what rate the duration of a fixed-income instrument will change while its profitability changes.
In its application to the field of mirrors, we have that, a convex mirror is one that has an outward curvature and its function is to generate a wide view of the environment they reflect.
