The radius of curvature and the focal length mean the same so the radius of curvature is also 15 cm.

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.
Why the focal length of concave mirror changes in water?
I don't think so. The focal length would remain the same. It mainly depends on the radius of curvature of the mirror.
What is the Focal length of a concave mirror?
It is the point , on the central axis, where light, that is parallel to the central axis, passes thru after it is reflected from the mirror. It is also at a distance from the mirror equal to twice the radius of curvature of the mirror.
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.
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.
What are the properties of images that a concave mirror can produce?
there is an imaginary point in front of the concave mirror, called the focal point or focus, which is half the length of the radius of the sphere of which the mirror was a part of(radius of curvature). usually an object if seen in between the mirror and focus gets magnified, beyond the focus, it gets inverted and reduced.

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 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.
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 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.
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.
How can a spherical mirror become a plane mirror?
By increasing its radius of curvature to infinity.
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.
