What is the focal length of concave mirror of radius 20cm?
The focal length of a concave mirror is half of its radius of curvature. Therefore, for a concave mirror with a radius of 20 cm, the focal length would be 10 cm.
What is the focal length of concave mirror to form real image?
The focal length of a concave mirror to form a real image is positive. It is equal to half the radius of curvature (R) of the mirror, and the image is formed between the focal point and the mirror.
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.
What is the relationship between curvature and focal length?
Curvature and focal length are inversely related. A shorter focal length corresponds to more curved surfaces, while a longer focal length results in flatter surfaces. This relationship is seen in various optical systems like lenses and mirrors.
What happens to the size of a real image when it's between c and f?
When the object is located between the center of curvature (C) and the focal point (F) of a concave mirror, the real image appears magnified and is located beyond the center of curvature. This is due to the converging nature of concave mirrors when the object distance is within the focal length.
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 is the relationship between focal length and radius of curvature?
R = 2f

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.

When the object is located between the center of curvature (C) and the focal point (F) of a concave mirror, the real image appears magnified and is located beyond the center of curvature. This is due to the converging nature of concave mirrors when the object distance is within the focal length.
What is curvature of a lens?
The curvature of a lens refers to the amount of bending in the lens surface. A lens can have a convex curvature (outward bending) or a concave curvature (inward bending), which affects how it refracts light. Curvature is measured by the radius of curvature, which can determine the focal length and strength of the lens.
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 nature of the image produced by a concave mirror if the object lies beyond twice of focal length?
If the object lies beyond twice the focal length of a concave mirror, a real and inverted image is produced between the focal point and the mirror's center of curvature. The image is diminished in size compared to the object.
What is relation between focal length and radius of curvature in lenses?
The Center of curvature is 2 times the focal length. By the way this is a physics question.
