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 plane mirror?
The center of curvature of a plane mirror is located at an infinite distance behind the mirror. This is because a plane mirror is flat and does not have a curved surface like a concave or convex mirror.
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.
True or false the center of curvature of a plane mirror is at infinity?
False. The center of curvature of a plane mirror is not at infinity, but rather it is located at a point behind the mirror at a distance equal to the radius of curvature.
Is plane mirror a spherical mirror why?
No, a plane mirror is not a spherical mirror. A plane mirror has a flat reflective surface, while a spherical mirror has a curved reflective surface. The shape of the mirror affects the way light is reflected, with spherical mirrors causing light rays to converge or diverge depending on their curvature.
What is definition for the centre of curvature of a spherical mirror?
The center of curvature of a spherical mirror is the point at the center of the sphere from which the mirror is a part. It is located at a distance equal to the radius of the sphere. The center of curvature is an important point for determining the focal length and the magnification of the mirror.
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).
WHAT HAPPENS TO THE FOCAL LENGTH OF A CONCAVE MIRROR AS THE CURVATURE OF THE MIRROR IS INCREASED?
As the curvature of a concave mirror is increased, the focal length decreases. This means that the mirror will converge light rays to a focal point at a shorter distance from the mirror. The mirror will have a stronger focusing ability.
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
What are the parts of convex mirror?
A convex mirror consists of a reflective surface that curves outward, away from the observer. It also has a focal point located behind the mirror and a center of curvature, which is the midpoint of the mirror's curvature.
What factor influences the image produced by reflection of an object in a concave mirror?
Distance from the mirror, curvature of the mirror.
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.
