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.
What is the radius of curvature of cornea of human eye?
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.
Will a sharp metal point with a small radius curvature store a large or small amount of charge?
There are two limits to how much charge a perfect conductor can store. One is determine by its area and has nothing to do with sharpness or radius of curvature. Thus, a larger area can store more charge than a smaller area. However, the other limit on the maximum stored charge is when the potential reaches the breakdown voltage and then an arc occurs. This breakdown voltage is easier to achieve when the object is sharp and thus ultimately it will indeed store less charge.
The radius of curvature is 10 ft and the height of the segment is 2 ft what is the length of the chord?
To find the length of the chord, you can use the formula for the length of the chord in a circle segment: Chord length = 2 * sqrt(r^2 - h^2) where r is the radius of curvature (10 ft) and h is the height of the segment (2 ft). Plugging in these values, you get Chord length = 2 * sqrt(10^2 - 2^2) = 2 * sqrt(96) = 2 * 4 * sqrt(6) = 8 * sqrt(6) ft.
What is the scientific name of radius?
The scientific name of radius is "radius." Radius is one of the two long bones in the forearm, located on the lateral side of the arm when in the standard anatomical position.
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.
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 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 a concave mirror has a radius of curvature of 40.5 cm. how far is the mirror from the persons face?
The focal length of a mirror with a radius of curvature of 40.5 cm is half of the radius, so it is 20.25 cm. The mirror's face would be placed around this focal length distance from the person's face for optimal viewing.
If A Concave Mirror Of Radius Of Curvature cm Produces An Inverted Image 4 Times The Size Of An Object Placed On And Perpendicular To The Axis. Determine By An Accurate Scale The Position Of the objec?
If the image produced is 4 times the size of the object and inverted, then the object is placed at a distance equal to half the radius of curvature from the mirror. This would position the object beyond the center of curvature of the concave mirror. Using an accurate scale, you would measure a distance of half the radius of curvature from the mirror to locate the object.
For very small angles the focal length of a concave mirror is?
For very small angles, the focal length of a concave mirror is approximately half of the radius of curvature of the mirror. This is known as the mirror equation and holds true for small angles under the paraxial approximation.
How far from a concave mirror radius 28.6 cm must an object be placed if its image is to be at infinity?
The object must be placed at a distance equal to the radius of curvature of the concave mirror in order for its image to be at infinity. In this case, the object must be placed 28.6 cm away from the concave mirror.
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.
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 Focal length of a concave mirror?
It is the point , on the central axis, where light, that is parallel to the central axis, passes thru after it is reflected from the mirror. It is also at a distance from the mirror equal to twice the radius of curvature of the mirror.
What is the center of curvature of a mirror?
A plane mirror is not curved so it does not have a center of curvature. Or if you want to be mathematically correct, you could say that it's center of curvature is at an infinite distance from the mirror.
