The focal length is half the radius of curvature and is as f=R2, where f is the focal length, and R is the radius of curvature. Convex and Concave Mirrors Convex and concave mirrors are sections of a whole sphe
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, then the dist...
An object which has a height of 12.5 cm , is placed 45.0 cm in front of a concave , spherical mirror, which has a focal length of 15.0 cm: a) What is the radius of curvature of this mirror? b) What will be the position of the result...
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)
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...

Focal Length:It is a fundamental concept in optics. Focal length is defined as the distance between the lens or mirror and the focal point (half of the radius of curvature of a lens/mirror). W...
Focal length of a spherical lens is equal to half of its radius of curvature. It is positive for the convex lens; however, the focal length of a concave lens is negative. According to the sign convention, the image and object distanc...
