8 Ft it cant be 8 it is ether 7.5 ft or 10 ft or 12 ft or 15 ft
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.
The image of the star will be 67.5 cm from the mirror because focal length is the raidus of curvature multiplied by 2 or (2)(C). So, therefore, 150 / 2 will give the focal length which would also be the answer.
The average radius of curvature of the cornea in a human eye is approximately 7.8 mm. This curvature plays a crucial role in focusing light onto the retina for clear vision. Changes in the radius of curvature can affect the eye's refractive power and lead to vision problems like nearsightedness or farsightedness.
Blood vessel radius has a larger effect on the body because changes in radius significantly impact blood flow resistance, which affects blood pressure regulation and delivery of oxygen and nutrients to tissues. Vessel length, on the other hand, has a smaller direct effect on blood flow resistance and overall cardiovascular function.
the formula for the radius of any regular polygon is: r=s/(2 sin (π/n)) where r = radius, s = length of side n = number of sides (in this case 12) and of course π = 3.14 Sin is in radians.
The radius of curvature is the distance from the center of a curved surface or lens to a point on the surface, while the center of curvature is the point at the center of the sphere of which the curved surface is a part. In other words, the radius of curvature is the length of the line segment from the center to the surface, while the center of curvature is the actual point.
radius of curvature = 2Focal length
Radius of curvature divided by tube diameter. To get the radius of curvature, imaging the bend in the tube is a segment of a circle, the radius of curvature is the radius of that circle.
12 ft
Assume that the height of the segment is h, the chord length is c and the radius is r then: r2=(r-h)2+(c/2)2 (We join two radii to the two ends of the chord then extend the height of the segment to the center of the circle in which the segment is inscribed so this height will bisect the chord and you use the pythagorean theorem to find the radius)
The curvature of the radius of a lens affects its focal length and optical power. A lens with a shorter radius of curvature will have a shorter focal length and higher optical power, while a lens with a larger radius of curvature will have a longer focal length and lower optical power.
In a concave mirror, the radius of curvature is twice the focal length.
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.
No, the focal length and radius of curvature of a lens cannot be the same. The radius of curvature is twice the focal length for a lens. This relationship is based on the geometry of the lens and the way light rays converge or diverge when passing through it.
The radius of curvature and the focal length mean the same so the radius of curvature is also 15 cm.
The relation between focal length (f), radius of curvature (R), and the focal point of a spherical mirror can be described by the mirror equation: 1/f = 1/R + 1/R'. The focal length is half the radius of curvature, so f = R/2.
When the curvature radius is larger, the focal point moves closer to the lens or mirror. This is because the curvature radius affects the focal length – a larger radius results in a shorter focal length and thus a closer focal point.
