How is power of lens related to radius of curvature?

Lens surface power can be found with the index of refraction and radius of curvature. The formula for surface power is Ds = (u-1)/r, where u is the index of refraction and r the radius of curvature in meters.

What is the relationship between radius of curvature and focal length of lens?

The relation between focal length (f) and radius of curvature (R) of a spherical mirror is that the focal length is equal to half of the radius of curvature i.e. f=R2.

What is the relation between power of lens and its focal length?

The optical power of a lens is equal to the reciprocal of the focal length of the lens. P = 1/f. SI unit of power is dioptre (D) and that of focal length is metre (m).

What is the relation between refractive index and radius of curvature?

When the plane surface of the lens in contact with the table, the image of center of the plane face is formed due to refraction at curved surface. The image of O is formed at I2. ∴v2μ2−u2μ1=R2μ2−μ1 gives.

What is the relation between the focal length of a lens and its power direct or inverse?

Magnifying power is inversely related to the focal length of a lens: the bigger the focal length, the lower the magnifying power.

What is meant by power of a lens ‘? How power of a lens is affected by its curvature?

The power of a lens is the degree to which a lens converges or diverges the light incident on it. Now, this convergence or divergence will depend on how much the lens is curved. A lens which is higly curved means that it will have high convergence or divergence to offer to the incident light.

What is the relation between radius of curvature and focal length of a lens if the radius of curvature of a lens is 30cm find its focal length?

= 1/2 X 30 = 15cm.

What is relation between radius of curvature and focal length class 10?

Radius of curvature is observed to be equal to twice the focal length for spherical mirrors with small apertures. Hence R = 2f .

Which relation of power of lens are correct?

The reciprocal of a lens’ focal length in metres equals its power. This means they both share an inverse relation. Because a lens’s power is inversely proportional to its focal length, a lens with a short focal length has more power and a lens with a long focal length has less. Hence, statement A is correct.

What is the relation between power of lens P and its focal length f answer in one word?

It is equal to the reciprocal of the focal length of the device: P = 1/f.

What does refractive power of lens depend on?

It depends on the difference between the refractive index of the lens and that of the surrounding medium: the bigger the difference, the stronger the lens. If those are the same, the lens is no longer a lens.

What is the relation between refractive index and focal length?

Relationship between the power of a convex lens and the refractive index of a medium. Apparently, focal length f is inversely proportional to the refractive index of the medium μ. Since, Optical Power P=1f. This should imply that optical power is directly proportional to the refractive index.
