Breathtaking Derive The Lens Maker Formula
Derive the formula.
Derive the lens maker formula. We assume a thin converging lens and that the light rays we are dealing with are close to the principal axis and make very small angles with the principal axis angles of less than 10 o resulting in very small angles of incidence.

In this session Tushar sir will be discussing the topic Lens Maker Equations Mirror Formula with practice multiple choice questions from Class 10 Physic.
This formula is only applicable to a lens. Derive lens makers formula for a thin convex lens. Thus for u v f.
We will discuss the form of the equation that is applicable only to thin lenses. Lens formula is applicable for convex as well as concave lenses. Write the basic assumptions used in the derivation of lens makers formula and hence derive this expression.
The focal length of a lens depends upon the refractive index of the material of the lens and the radii of curvatures of the two surfaces. Lens Maker Formula Derivation. Asked Oct 18 2019 in Physics by KumarManish 577k points cbse.
Lens Maker Formula With Derivation The formula giving the relation between the focal length f of the lens the refractive index of the material of the lens n and the radii of curvature of its surface R 1 R 2 is known as Lens maker formula. Join the 2 Crores Student community now. Adding ii and iii If the object O is taken far away from the lens the image is formed close to the focus.
Watch 1 minute video. The Lens Makers Formula is an expression used to find the focal length of a lens for which the refractive index as well as the radii of curvature are known. Basic assumptions in derivation of Lens-makers formula.
