Which is the line joining the centre of curvature and pole?
The line joining the center of curvature and the pole of a mirror is known as the "radius of curvature." The center of curvature is the center of the sphere from which the mirror is a part, while the pole is the midpoint of the mirror's surface. This line is crucial in understanding the geometric properties of mirrors and their reflective behavior.
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.
If the focal lenght of a concave mirror is 15 cm find the radius of curvature?
The radius of curvature and the focal length mean the same so the radius of curvature is also 15 cm.
How to derive the centre of curvature?
This involves the rate of change of the unit tangent vector. Deriving the curvature starts with the equation of a circle. Then three equations that force the collocation circle to go through the three points and on the curve must be written down. Then solve for a, b, and r.
What is the difference between the measure of an arc and arc length?
They are normally the same. However, the measure of the arc could refer to the angle subtended at the centre of the radius of curvature.
What is definition of centre of curvature of lens?
define the term centre of curvature
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.
Where will the image form when you place an object on the principal axis of a concave mirror at a point between focus and centre of curvature?
If the object is placed on the principal axis of a concave mirror at a point between the focus and centre of curvature the image will form beyond the centre of curvature
How will a ray directed towards the centre of curvature of a convex mirror be reflected?
A ray directed towards the centre of curvature of a convex mirror will reflect back on itself along the same path. This is because the centre of curvature is located on the normal line, so the angle of incidence and the angle of reflection will be equal due to the principle of reflection.
Is the radius In math?
It is the distance, from any point on a curve, to the centre of curvature at that point.
What is the difference between Radius of curvature and centre of curvature?
The radius of curvature is the distance from the center of a curved surface or lens to a point on the surface, while the center of curvature is the point at the center of the sphere of which the curved surface is a part. In other words, the radius of curvature is the length of the line segment from the center to the surface, while the center of curvature is the actual point.
What is the center of curvature of the mirror?
The center of curvature of a mirror is the point located at a distance equal to the radius of curvature from the mirror's vertex. It is the center of the sphere of which the mirror forms a part. Light rays that are reflected from the mirror and pass through this point are either parallel to the principal axis (for concave mirrors) or appear to diverge from this point (for convex mirrors).
A line joining pole and centre of curvature of the mirror is called?
The line joining the pole and the centre of curvature of a mirror is called the principal axis. This line is a key reference point for determining the focal length and characteristics of the mirror.
What is mathimatical radious?
In mathematics, the radius of an arc is a straight line from the centre of curvature of the arc to the arc. In the case of a circle it is the line from the circle's centre to its circumference.
What is the exact relation of the focal length to the center of curvature?
The focal length (a.k.a focus) is exactly half the length of the centre of curvature. ie. F = 1/2 C
Which is the line joining the centre of curvature and pole?
The line joining the center of curvature and the pole of a mirror is known as the "radius of curvature." The center of curvature is the center of the sphere from which the mirror is a part, while the pole is the midpoint of the mirror's surface. This line is crucial in understanding the geometric properties of mirrors and their reflective behavior.
