The focal point of a concave mirror is 5 cm what is its center of curvature?
10 cm from the mirror.
Is the focal length equal to the radius of curvature of the mirror?
yes
What is the relation between focal length and center of curvature?
The focal length of a concave mirror is about equal to half of its radius of curvature.
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.
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 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.
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 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.
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.
How do you derive relation between focal length and radius of curvature of convex mirror?
the curvature mirror the emage of the mirror is virtual
What is the center of curvature of the mirror?
the centre of sphere is known as centre of curvature
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 factor influences the image produced by reflection of an object in a concave mirror?
Distance from the mirror, curvature of the mirror.
What is the plane mirror explain formation of images by a plane mirror?
the image in a plane mirror is always
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 definition for the centre of curvature of a spherical mirror?
It is the center of the imaginary sphere to which the mirror belongs.
Why is the focal length of a plane mirror infinity?
In a plane mirror, the radius of curvature is infinitly long, so the focus will be at infinity. Another way to say it is that a plane mirror has no curvature, and as curvature becomes increasingly small, focal length becomes increasingly long. At a curvature of zero, focal length becomes infinite. Focal length(f) is given by f=R/2 where R is radius of curvature.. Once again, it's infinity! See answer to your question on radius of curvature. Plug infinity (radius of curvature) into your mirror equation to get the focal length, which will also be infinite. A flat mirror does not focus incoming parallel beams. That's because if you say its at infinity it means it does exist in a finite distance, that is instead of saying it does exist its taken at infinite distance for only theoretical importance and not for practical observance. Focal length is half of radius of curvature of the mirror. So bigger the circle gets the more its radius will be. So in the same way as the curvature of the sphere gets less and less its focal length increases, so when it becomes totally flat the focal length will become infinite so it means it has no existence but it has only theoretical importance. It same as taking the formation of image of an object at principal focus to be at infinite distance rather than saying it does not form ( that is both mean the same). hope my answer is satisfactory
