Convex
Yes, technically a curved line can be a line segment, a line in general is something that can be curved or straight
A sphere has a total curved surface. A cylinder and a cone have a partial curved surface
depends i meen ice can have a curved surface
polygons can't have any curved sides
A mirror that is curved outward is convex. A mirror that is curved inward is concave.
Curved or rounded outward
Convex
The reflecting surface of a mirror is flat.
A lens curved outward is called a convex lens. This type of lens is thicker at the center than at the edges and causes light rays passing through it to converge to a focal point.
In geography, convex refers to a landform or terrain that bulges outward in a rounded or curved shape, often resembling a dome or hill. This term is commonly used to describe features such as mountain peaks or hillsides that curve gently outward.
Convex lenses are curved inward. Concave lenses curve outward.
A "concave" mirror curves inward. A "convex" mirror curves outward.
A lens that is curved outward is called a convex lens. This type of lens is thicker at the center and thinner at the edges, causing light rays passing through it to converge. Convex lenses are commonly used in magnifying glasses and camera lenses.
Do you know the Sakabato sword? On the normal Katana, the outward curved side of the blade is sharpened, while the inward curved side of the blade is blunt.
A convex mirror curves outward, causing light rays to diverge. This type of mirror is often used in security mirrors, car side-view mirrors, and as a safety feature in public spaces to provide a wider field of view.
Plane mirrors have a flat reflecting surface, while curved mirrors have a reflecting surface that is curved either inward (concave) or outward (convex). Curved mirrors can focus or diverge light rays depending on their shape, resulting in different optical properties compared to plane mirrors. Additionally, curved mirrors have a focal point and focal length, which plane mirrors do not possess.
