In optics, the relationship between the distance of the image (v), the distance of the object (u), and the focal length (f) of the lens is given by the formula known as the Lens formula. The Lens formula is applicable for convex as well as concave lenses.
Apr 16, 2024 · What is lens Formula. This formula denotes relationship between. Object Distance (u) Image Distance (v) Focal length (f) Note : - We follow the sign convention for lenses. In the image, the red text is negative, and blue text is positive. Thus, If Virtual image is formed,v is negative. If Real Image is formed, v is positive.
Jun 20, 2024 · In optics, the relationship between the distance of an object (o), the distance of an image (i), and the focal length (f) of the lens are given by the formula which is known as the Lens formula. Lens formula is applicable for concave as well as convex lenses. These lenses have negligible thickness.
Oct 27, 2022 · The lens formula is a mathematical equation used to determine the relationship between the object distance, image distance, and focal length of a lens. It is commonly used in optics to calculate the position and characteristics of images formed by lenses. The formula is given as: 1/f = 1/v – 1/u. Where: – f is the focal length of the lens.

The lensmaker’s formula relates the radii of curvature, the index of refraction of the lens, the thickness of the lens, and the focal length. If the lens is biconcave, a beam of light passing through the lens is diverged (spread); the lens is thus called a negative or diverging lens.
Jan 13, 2024 · The lens formula is a fundamental equation in optics that helps determine the properties of a lens. It relates the focal length, object distance, and image distance of a lens, and is expressed as follows: 1/f = 1/v - 1/u where f is the focal length, v is the image distance, and u is the object distance.
Let's explore the magnification formula (M= v/u) for lenses and see how to find the image height and its nature (whether it's real or virtual). Created by Mahesh Shenoy.
Jun 20, 2024 · The Lens formula is given below. 1/v - 1/u = 1/f. Here, "v" is the distance of the image from the optical center of the lens, "u" is the distance of the object from the optical center of the lens and "f" is the focal length of the lens.
Using the lens formula can be tricky because we need to substitute using signs. In this video, we will take one example and discuss how to use the lens formula. Created by Mahesh Shenoy.
