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.
3 days ago · 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.
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.
The lens equation expresses the quantitative relationship between the object distance (do), the image distance (di), and the focal length (f). The equation is stated as follows: The magnification equation relates the ratio of the image distance and object distance to the ratio of the image height (h i) and object height (h o ).
The video provides a detailed walkthrough of deriving the lens formula, which relates the object distance, image distance, and focal length in a convex lens. It uses similar triangles and algebraic manipulation to arrive at the formula \ [1/f = 1/d_0 + 1/d_i\], a key concept in optics for premed students.Created by Sal Khan. Questions Tips & Thanks
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.
