The best answer here is INFINITY, as all the formulas of geometrical optics will give you answers that make sense for plane mirrors by setting the radius to infinity.

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.


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?

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.


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.
