If the surface of a concave mirror is made more curved what happens to its focal length?

A concave mirror is a spherical mirror with a reflective inside surface. When the reflective surface is made more curved, the distance between the focal point and the surface increases. A concave mirror can form both virtual or real images.

What is the difference between area of curved surface of cylinder and surface area of cylinder?
Curved surface area includes the area of the length of the cylinder only whereas surface area includes the two bases as well...
What is a lateral area of a cone formula?
The curved surface area of a cone is: pi*radius*slant length.
A cone of height 24cm has a curved surface area of 550cm sq find it's volume?
Curved surface area = pi*radius*slant length Voume in cubic cm = 1/3*pi*radius2*height
What is the formulae for finding the curved surface area of a frustum of a cone?
The frustum of a cone looks like a plant pot and its curved surface area is: pi*(r1+r2)*l whereas r1 is the top radius and r2 is the bottom radius with l being its slanted length.
What is the surface are of a prism?
A prism is a generic term used to describe a polyhedron with two parallel and congruent polygonal bases and a number of rectangles joining the two bases. The bases can also be curved, in which case they are joined by a curved surface. The total surface area of a prism will be 2*area of base + perimeter of base*length of prism.
What is the different between concave and convex mirror light?
Concave mirror would have the surface curved out get coated with mercury hence curved in surface would reflect the rays fallen on. But convex mirror would have the surface curved in get coated with mercury hence curved out surface would reflect the rays fallen on. Concave mirror would have both converging and diverging ability. When light coming from an object placed at a distance higher than its focal length right from the pole of the mirror, converging takes place. But the object lies in between pole and the focus diverging action. But in convex mirror irrespective of the placement of the object only diverging phenomenon. Concave mirror used as shaving mirror and dentists too use them Convex mirror is used as rear view mirror in case of vehicles near by the driver.
Curved surface area of a cylinder?
2 x Pi x radius x height or length = curved surface area
What is the difference between area of curved surface of cylinder and surface area of cylinder?

How is curved surface area related to cylinder?
If cylinder radius and cylinder length are known : (pi = 3.141592654 . . . ) > Surface area = ( (2 * pi * radius) * length )
Will the focal length of concave lens change in water?
no, because this happens only in the cases of lenses
What is the formula for all surface areas?
Curved Surface Area = 2πr2Total Surface Area= (2πr2) + (πr2) = 3πr2
Formula for area of cone?
Curved surface area of a cone = pi*radius*slant length
Suface area of cone?
Curved surface area of a cone = pi*radiud*length of slant
What happens to images that are closer to a concave mirror than the focal length?
The image is upright and magnified/enlarged.
What is a lateral area of a cone formula?
The curved surface area of a cone is: pi*radius*slant length.
What is the equation for the Surface Area of a cylinder?
If the cylinder has radius R and length L , the curved part of the surface has area 2piRL and each of the ends has area piR^2. The total surface area is the sum of the curved part plus two ends.
How can a rough value of the focal length of a concave mirror be obtained?
