Yes, radius of curvature is longer than focal length for both types of lenses (O1 and O2 are the centers of curvature, F is focal point): Yes, curvatures of lens surfaces (R1 and R2) along with refractive index of lens material (n) affect its focal length (F) , hence the position...

To find the relationship between focal length (f) and radius of curvature (R), we can follow these steps:1. Understanding the Concepts: - A lens or mirror can be thought of as a part of a sphere. The radius of curvature (R)
Why the focal length of a spherical mirror has a smaller magnitude than that of its radius of curvature?Focal Length:In optics, focal length represents the distance between the centre of the mirror or lens (which is also known as a pole) and the focal p...
The image formed by concave mirror is always real except when the object is placed between pole and focus. The image formed by the convex mirror is always virtual. The radius of curvature is double of magnitude focal length.Answer and Explanation: ...

Focal lengthFourier transformA procedure for the measurement of focal length and radius of curvature of a lens using coherent gradient sensing system and Fourier transform fringe analysis technique has been demonstrated. Light from the laser illuminates the specimen and the wavefront emerging from the ...
Answer to: A plano-convex lens is to have a focal length of 40 cm. It is made of glass of index of refraction 1.65. What radius of curvature is...
The focal length of a concave spherical mirror is equal to {eq}1 {/eq} meter. What is the radius of curvature of this mirror? Focal Length: The total distance within the focal points and the midpoint of the lens are generally indicated by ...
On substituting the slant angle of the moir 茅 pattern into the derived equation, the focal lengths and radius of curvatures could be determined. The experimental results successfully demonstrated the feasibility of the proposed method; the percent errors for focal length and radius of curvature ...
