What is a surface normal?
There is no such expression. The normal to a surface, at a given point is the radius of curvature of the surface, at that point.
What does curvature ratio mean in tubing?
Radius of curvature divided by tube diameter. To get the radius of curvature, imaging the bend in the tube is a segment of a circle, the radius of curvature is the radius of that circle.
What is the spherical radius of 1 foot?
It is the distance from the centre to all points on the surface of a sphere with a radius of 1 foot.
What is the radius of curvature?
The radius of curvature of a circle, or an arc of a circle is the same as the radius of the circle.For a curve (other than a circle) the radius of curvature at a given point is obtained by finding a circular arc that best fits the curve around that point. The radius of that arc is the radius of curvature for the curve at that point.The radius of curvature for a straight line is infinite.
Why is the sum of the angles of spherical triangles always larger than the sum of the angles of plane triangles?
Because, to allow for the curvature of the spherical surface, each angle must be slightly larger than its plane-surface equivalent.
The relation between focal length and radius of curvature of spherical mirror is?
The focal length of a convex mirror is half of its radius of curvature.
What is radius of curvature?
The radius of the sphere of which a lens surface or curved mirror forms a part is called the radius of curvature.
How can a spherical mirror become a plane mirror?
By increasing its radius of curvature to infinity.
Which doesnot change when spherical mirror is broken?
Its radius of curvature and its reflecting property
What is the ratio of focal length of a spherical mirror to its radius curvature?
The focal point of a convex mirror lies on the same side as the centre of curvature and is at a distance of half the radius of curvature from the optical centre.
What is a surface normal?
There is no such expression. The normal to a surface, at a given point is the radius of curvature of the surface, at that point.
How lens power change with curvature of lens surface?
The lens power increases as the curvature of the lens surface becomes steeper. A lens with a larger radius of curvature will have a lower power, while a lens with a smaller radius of curvature will have a higher power. This relationship is described by the lensmaker's equation, which relates the power of a lens to the refractive index of the lens material and the radii of curvature of its surfaces.
What are spherical mirrors?
The most curved mirrors are spherical mirrors. The centre of curved surface is called center of curvature. There are two kinds of spherical mirrors. Concave and convex mirror.
What is the difference between Radius of curvature and centre of curvature?
the center of curvature is the ORIGIN of the radius of curvature
What is surface area of spherical shell?
Surface area of a sphere = 4*pi*radius2 For a spherical shell, surface area = surface area of outer sphere - surface area of inner sphere = 4*pi*(outer radius)2 - 4*pi*(inner radius)2 = 4*pi*[ (outer radius)2 - (inner radius)2 ]
What does curvature ratio mean in tubing?
Radius of curvature divided by tube diameter. To get the radius of curvature, imaging the bend in the tube is a segment of a circle, the radius of curvature is the radius of that circle.
What is the spherical radius of 1 foot?
It is the distance from the centre to all points on the surface of a sphere with a radius of 1 foot.
