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 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 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 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.
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 size of a real image when it's between c and f?

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.
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.
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 is the significance of the center of curvature in a concave mirror?
The center of curvature in a concave mirror is important because it is the point where the mirror's surface is perfectly curved. Light rays that are parallel to the mirror's principal axis and strike the mirror will either converge or diverge at this point, depending on the mirror's shape. This point helps determine the focal length and image formation in concave mirrors.
How does the curvature of a concave lens affect the location of the focal point?
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.
Formula for the radius of the curvature of the concave lens?
radius of curvature is double of focal length. therefore, the formula is: 1/f = (n-1)[ 1/R1 - 1/R2 + (n-1)d/nR1R2] here f= focal length n=refractive index R1=radius of curvature of first surface R2=radius of curvature of 2nd surface d=thickness of the lens using this, if you know rest all except one, then you can calculate that.
