In a concave lens, the focal point is located on the same side as the incoming light rays. A more curved concave lens will have a shorter focal length, bringing the focal point closer to the lens surface.

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 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 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.


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 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.


The focal point of a concave mirror is 5 cm what is its center of curvature?

10 cm from the mirror.


A candle is placed between the center of curvature and the focal point of a concave mirror?

The image formed by the concave mirror will be located beyond the center of curvature, inverted, and smaller in size.


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 are the rules in concave mirror?

In concave mirrors, light rays that are parallel to the principal axis converge at the focal point. The rules for concave mirrors include: 1) light rays passing through the focal point reflect parallel to the principal axis, 2) light rays reflecting off the mirror pass through the center of curvature, and 3) the distance from the focal point to the mirror is half the 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 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.


Do thick concave lenses have longer or shorter focal lengths than thin concave lenses?

Thick concave lenses have shorter focal lengths than thin concave lenses. This is due to the increased curvature of the lens surfaces in thick lenses, which causes light rays to converge more quickly to a focal point.
