Additional Information
Concave objects or shapes can be found in everyday life, from the design of eyeglasses to satellite dishes. In engineering, concave surfaces are used to direct or distribute forces, heat, or light in specific ways. The word can also be applied to abstract concepts, such as the concave shape of a function in mathematics or the concave structure of an organizational chart in business. Concave surfaces can also be found in nature, such as in the shape of seashells or in the rock formations carved out by river currents.
Concave shapes are used extensively in various fields, including architecture, engineering, and product design.

For example, some sculptures or installations use concave shapes to create a sense of depth or mystery. Additionally, concave shapes can be used to create optical illusions or visual effects.
