What is the formula of focal length of mirror?

The focal length of a spherical mirror is given by f=R2, where R is the radius of curvature of the mirror. For a given spherical mirror made of steel, the focal length is f=24.0 cm.

How do you find the focal length of a concave mirror given the radius?

In other words, in the small-angle approximation, the focal length f of a concave spherical mirror is half of its radius of curvature, R: f=R2.

What is the formula for focal length of concave and convex mirror?

Suppose an object is placed u cm in front of a spherical mirror of focal length f such that the image is formed v cm from the mirror, then u, v and f are related by the equation; 1/f= 1/u + 1/v. This equation is referred to as the mirror formula. The formula holds for both concave and convex mirrors.

How do you calculate focal length?

The focal length is half the radius of curvature and is as f=R2 f = R 2 , where f is the focal length, and R is the radius of curvature.
