Yes, a concave shape curves inward, creating a hollow or recessed appearance. This shape can be commonly seen in caves, spoons, and certain types of mirrors.
The surface of each half of a boiled egg is concave. This is because the inside of the egg is curved inwards, creating a concave shape when the egg is split in half.
by shape
The manual menu in the restrant was awkwardly concave.
Concave shapes curve inward, like a cave, while convex shapes curve outward. To distinguish between them, you can look at the direction in which the shape curves - concave curves inwards, while convex curves outwards.
Concave lenses bend light rays outward (diverging) as they pass through, causing the rays to spread apart. This is due to the shape of the lens surface being thinner at the center than at the edges, which causes light rays to diverge.
Concave is not a shape, it is the term for when two lines meet facing inwards, rather than outwards (outwards is known as convex)
A concave mirror bends light inwards towards a central focal point. This type of mirror can focus light rays to create a real or virtual image, depending on the distance between the object and the mirror.
Concave
The word 'convex' refers to a shape that is curved outwards. In geometric terms, a convex shape bulges outward, resembling the exterior of a sphere or a dome. This is in contrast to 'concave,' which describes a shape that curves inwards.
bent or curved inwards
The surface of each half of a boiled egg is concave. This is because the inside of the egg is curved inwards, creating a concave shape when the egg is split in half.
Convex when it bends outwards, concave when it bends inwards
Such a mirror is concave.

no concave mirror is in shape of concave mirror
