View Solution A real image of half the size is obtained in a concave spherical mirror with a radius of curvature of 40 cm. The distance of object and its image will be View Solution A concave mirror of focal length produces an image m times the size of the object. If image is real,...
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)
Focal length:The focal length (denoted by FP in the fig.) is the distance between the pole P and the principal focus F of a curved mirror. The focal length is half the radius of curvature. Focal length = Radius of curvature/2 . Rules for constructing ray diagrams Any light ray travelin...
The center of curvature, C, refers to the center of the sphere by which the mirror is originally part. The distance from the mirror's vertex to the center of curvature is called the radius of curvature, R. The focal length is half the radius of curvature and is as f=R2, where f ...
in whichf= focal length of the refracting surface,n= index of refraction of the lens,R1= radius of curvature of the refracting surface facing the initial medium, andR2= radius of curvature of the refracting surface facing the final medium.Rvalues will be positive for concave lenses and nega...
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...
Usually, the below written mathematical relationship between the focal length of a lens, the refractive index of the lens's material is formed, and the radius of both curvatures of the lens is shown by the lens maker for...
