Sensational Derive Lens Maker Formula With Diagram

Assumptions used in the derivation of lens formula.

Derive lens maker formula with diagram. The concave lens creates an erect and virtual image II at a range of q from the optical center of the lens as shown in the below diagram. Now using this I have to derive Lens makers Formula. Hence obtain the expression for lens-makers formula in the case of thin convex lens.

PA x2 h212 x 12 X h2x. Class 10 Physics Light Reflection Refraction Asked by Rah 1 Answers. In this video learn how to derive lens formula for thin lens.

A lens maker formula may be defined as the formula which gives the relationship for calc. Derivation of lens formula for a convex lens. The refractive index of the material of lens is n 2 and it is placed in a medium of refractive index n 1The optical centre of lens is C and X X is principal axis.

Ask me anything. Suppose L is a thin lens. The medium on either side of the lens needs to be the same.

O C 1 II C 2 1 P 1 P 2 I2 B E A D u1 v1 v2 r1 r2 t n1 t v1 n2 n1 SF027 52 By using the equation of spherical refracting surface the refraction by first surface AB and second surface DE are given by. Lens Makers Formula - example Consider a convex lens or concave lens of absolute refractive index μ 2 to be placed in a rarer medium of absolute refractive index μ 1. Ii Where should an object be held from the lens so as to obtain a virtual image of magnification 2.

SF017 SF027 51 15 Thin Lenses Formula and Lens makers Equation Considering the ray diagram of refraction for 2 spherical surfaces as shown in figure below. Considering the refraction of a point object on the surface X P 1 Y the image is formed at I 1 who is at a distance of V 1. In this video learn how to derive lens maker formula for thin lens.
