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.

Curvature is a general term to describe a graph. Like, concave or convex.

Radius of curvature is more exact. If the curve in a 'small' section is allow to continue with the same curvature it would form a circle. that PRETEND circle would have an exact radius. That is the radius of curvature.

radius of curvature = 2Focal length

The radius of the sphere of which a lens surface or curved mirror forms a part is called the radius of curvature.

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.

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.

The radius of curvature of a lens is the distance between the center of the lens and its focal point. It is a measure of the curvature of the lens surface. A smaller radius of curvature indicates a more curved lens, while a larger radius indicates a flatter lens.

The radius of curvature and the focal length mean the same so the radius of curvature is also 15 cm.

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.

The radius of curvature is important in physics because it determines the curvature of a wavefront or a mirror or lens surface. In the case of light or other waves, the radius of curvature affects how the waves are focused or dispersed. A smaller radius of curvature results in a more curved surface, which can focus light or waves to a point, while a larger radius of curvature leads to a flatter surface that disperses the waves.

In a concave mirror, the radius of curvature is twice the focal length.

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.

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 curvature of the Earth in any direction can be calculated using the formula for the Earth's radius of curvature (R), which is given by R = a / √(1 - e^2sin²φ) where a is the equatorial radius of the Earth and e is the eccentricity of the Earth. By determining the radius of curvature at a specific latitude (φ), you can find the curvature in that direction.

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.

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 lens power increases as the curvature of the lens surface becomes steeper. A lens with a larger radius of curvature will have a lower power, while a lens with a smaller radius of curvature will have a higher power. This relationship is described by the lensmaker's equation, which relates the power of a lens to the refractive index of the lens material and the radii of curvature of its surfaces.

The focal point of a convex mirror lies on the same side as the centre of curvature and is at a distance of half the radius of curvature from the optical centre.

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.

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.

The formula for the radius of curvature (R) of a double convex lens is given by R = 2f, where f is the focal length of the lens. The radius of curvature is the distance from the center of the lens to the center of curvature of one of its curved surfaces.

The focal length of a concave mirror is about equal to half of its radius of curvature.

Radius of curvature in Newton's rings is the radius of the curvature of the wavefront at the point where interference fringes are observed. It is calculated by measuring the diameter of the nth dark ring and using the formula R = (n * λ * D) / (2 * δ), where R is the radius of curvature, n is the order of the ring, λ is the wavelength of light, D is the distance between the lens and the glass plate, and δ is the diameter of the nth dark ring.

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.

A lens with a large radius of curvature allows for a greater region of interference fringes to be observed, making it easier to measure the diameter of the rings accurately. This increases the precision of the experiment and reduces errors in measurement. Additionally, a large radius of curvature reduces the curvature of the lens surfaces, leading to more uniform and symmetrical interference patterns.

R = 2f

Tangent continuity: No sharp angles.

Curvature continuity: No sharp radius changes.

The center of curvature of a lens is the point located at a distance equal to the radius of curvature from the center of the lens. It is the point where the principal axis intersects the spherical surface of the lens.

The Center of curvature is 2 times the focal length.

By the way this is a physics question.

f=|-R/2|

By increasing its radius of curvature to infinity.

There is not enough information to answer the question.

Its radius of curvature and its reflecting property

It is the distance, from any point on a curve, to the centre of curvature at that point.

Radius of rings is directly proportional to the square root of the radius of curvature. Thin lens would have larger radius of curvature and hence the option

The curvature of a convex lens refers to the amount of curvature or bend present on each of its surfaces. It is typically defined by the radius of curvature, which indicates how sharply the lens surface is curved. This curvature plays a significant role in determining the focal length and optical properties of the lens.

The formula for calculating the parabola radius of curvature at a specific point on the curve is: R (1 (dy/dx)2)(3/2) / d2y/dx2, where R is the radius of curvature, dy/dx is the first derivative of y with respect to x, and d2y/dx2 is the second derivative of y with respect to x.

The focal length of a lens is related to its radius of curvature and the index of refraction by the lensmaker's equation: [\frac{1}{f} = (n-1) \left( \frac{1}{R_1} - \frac{1}{R_2} \right)] Given the radius of curvature (R = 0.70 , m) and the index of refraction (n = 1.8), you can calculate the focal length.

The formula for calculating the radius of curvature of a parabola at a specific point on its curve is given by the equation: R (1 (dy/dx)2)(3/2) / d2y/dx2, where R represents the radius of curvature, dy/dx is the first derivative of y with respect to x, and d2y/dx2 is the second derivative of y with respect to x.

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 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.

You need to do your differentiation in terms of polar coordinates

There is no such expression. The normal to a surface, at a given point is the radius of curvature of the surface, at that point.
