A plane horizontal surface with no depth refers to a flat area on a curved surface.
When the two surfaces touch but do not intersect one another.
It has a curved surface.
A tangent
A surface is a 2-dimensional manifold. Most surfaces are curved, in which for a small "differential" section of a surface, a plane figure is uniquely determined.
A surface having no equivalent point at any plane
A plane horizontal surface with no depth refers to a flat area on a curved surface.
It is a mirror whose reflecting surface is curved, not flat (as in a plane mirror).
a plane
None. There is one curved suface but no plane surface.
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.
When the two surfaces touch but do not intersect one another.
Yes, but not on a plane surface; only on a curved surface.
It has a curved surface.
It is a mirror whose reflecting surface is curved, not flat (as in a plane mirror).
