Convex is usually bigger than concave. In a convex shape, an imaginary line connecting any two points lies completely within the shape, making it appear more expansive. In contrast, a concave shape curves inward, often providing less surface area than a convex shape of similar dimensions.

What are the types of lenses and mirrors?
Lenses: converging (convex) and diverging (concave) Mirrors: concave and convex
What is the opposite of concave?
The opposite of concave is convex. A concave surface curves inward, while a convex surface curves outward.
Can lenses be planar convex or concave?
Yes, lenses can be planar convex or concave. A planar convex lens has one flat surface and one convex surface, while a planar concave lens has one flat surface and one concave surface. These types of lenses are less common compared to standard convex and concave lenses.
Is a cross concave or convex?
It depends on the specific orientation of the cross. A cross can have both concave and convex elements depending on the angles and alignment of its branches.
Is a magnifying glass convex or concave?
