What is difference between curvature and radius of curvature?
Curvature is a general term to describe a graph. Like, concave or convex. Radius of curvature is more exact. If the curve in a 'small' section is allow to continue with the same curvature it would form a circle. that PRETEND circle would have an exact radius. That is the radius of curvature.
What is the curvature of circle having radius a?
1/aAccording to Wikipedia,"The canonical example of extrinsic curvature is that of a circle, which has curvature equal to the inverse of its radius everywhere. Smaller circles bend more sharply, and hence have higher curvature. The curvature of a smooth curve is defined as the curvature of its osculating circle at each point."
Definition of plane mirror?
A plane mirror is a mirror which is completely flat, easier for your image to be reflected.
What is the term for a mirror with a flat surface?
plane mirror
Which is correct plane mirror or plain mirror?
A plane mirror is a flat, as opposed to convex or concave, mirror.A plain mirror is just a ordinary mirror as used in a household. These are usually flat mirrors so they are also plane mirrors.Many households have small bathroom mirrors which magnify in this case they would be concave plain mirrors and not concave plane mirrors
How can a spherical mirror become a plane mirror?
By increasing its radius of curvature to infinity.
What is the center of curvature of a mirror?
A plane mirror is not curved so it does not have a center of curvature. Or if you want to be mathematically correct, you could say that it's center of curvature is at an infinite distance from the mirror.
True or false the center of curvature of a plane mirror is at infinity?
Plane mirrors don't have one, I'd say it was 0.
What is the relationship between the radius of curvature and focal length in a concave mirror?
In a concave mirror, the radius of curvature is twice the focal length.
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.
The relation between focal length and radius of curvature of spherical mirror is?
The relation between focal length (f), radius of curvature (R), and the focal point of a spherical mirror can be described by the mirror equation: 1/f = 1/R + 1/R'. The focal length is half the radius of curvature, so f = R/2.
How can find the radius of curvature?
There is a specific formula for finding the radius of a curvature, used often when one is measuring a mirror. The formula is: Radius of curvature = R =2*focal length.
What is the center of curvature of a plane mirror?
A plane mirror is not curved so it does not have a center of curvature. Or if you want to be mathematically correct, you could say that it's center of curvature is at an infinite distance from the mirror.
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.
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.
Is the focal length equal to the radius of curvature of the mirror?
yes
What is a concave mirror has a radius of curvature of 40.5 cm. how far is the mirror from the persons face?
The focal length of a mirror with a radius of curvature of 40.5 cm is half of the radius, so it is 20.25 cm. The mirror's face would be placed around this focal length distance from the person's face for optimal viewing.
