NO it cannot be. Because radius of curvature is given by the expression R = 2 f

What is the relation of focal length of eye with its curvature?
More the curvature of the eye lens, lesser the focal length is. Lesser the curvature, greater the focal length is
How does change in the thickness of lens change the focal length of lens?
Not at all. The focal length is determined by the curvature of the surfaces.
Formula of radius of curvature of double convex lens?
Radius of curvture = twice the focal length of the double convex lens In symbols R = 2*f or f = R/2 Hope u seek the same
The focal point of a lens depends on which two things?
Radius of curvature and refractive index of the material
Lenses are engineered to have specific focal lengths Besides the curvature of the two sides of a lens what determines the focal length?
The material that the lens is made from.

Why does the focal length of a mirror not depend on the mirror material when the focal length of a lens does depend on the lens material?
The focal length for a mirror is determined by the law of reflection from the mirror surface. This law is not governed by the material that the mirror is made by. This means that the focal length depends only on the radius and curvature. Conversely, the focal length of a lens depends on the indices of refraction of the lens meterial and the surrounding medium.
If a telescope has an objective lens of 3 inches what is the focal length?
The size (diameter) of a lens does not determine its focal length. The amount of curvature of the lens does. Citing a diameter for a lens doesn't help us find the focal length. Lenses are ground to specifications that allow short or long focal length. The more curved the lens, the shorter the focal length. You can see this if we specify a given curvature and then start to "flatten" the lens. The focal length will get longer and longer as the lens is flattened. When the lens is flat (has to curvature) the lense has an infinite focal length, just like a piece of flat glass.
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 determines the focal length of two sides of a lens?
Their radii of curvature and the refractive index of the material of the lens.
How does thickness of convex lens affect focal length?
The focal length of a lens depends on 1. The refractive index of the material 2. Radii of the curvature of the two faces. The lens maker's formula is 1/f = (mu --1) (1/R1 --1/R2) mu- the refractive index of the material with which lens is made R1 and R2 are the radii of curvature of the faces. f- the focal length of the lens thus formed. your question needs clear information. As the thickness of the lens of same diameter is increased then radii of curvature would decrease, hence focal length would decrease. But as the diameter gets increased then there comes a chance of maintaining the radii of curvature to be the same. If so, then no change in the focal length. But, if diameter is not increased to the right extent then we cannot be sure about the variation of focal length.
How does the thickness of a lens affect the focal length of a lens?
There are three factors affecting the focal length of a lens. 1. refractive index of the material of lens. 2. refractive index of the surrounding medium 3. the radius of curvature of the lens surfaces.
What factor determines the focal length of a lens?
It is determined by the radii of curvature of its two faces.
