The focal length of a double convex lens is given by the formula (1/v) + (1/u) = (1/f), where u is the distance between the object and the lens, v is the distance between the image and the lens.

What is the formula for focal length lens?
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.
How do you find the focal length of?
To determine focal length of a convex lens
The position of the screen should be such that the sharp image of the distant object is obtained on it. The difference between the position of the lens and the screen is equal to the focal length of the given convex lens.
What is meant by focal length of a lens?
Focal length is defined as the distance between the optical centre and the focus of the lens.
