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.
Jun 13, 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.
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.
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.
