BC 1 R 1.
Write the basic assumptions used in derivation of lens maker formula. 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. Lens Maker Formula With Derivation. If you want me to teach you Biology or Chemistry or Physics.
Iv The object is a small object placed on the principal axis. As B and D bothare close to the optical centre of the lens BO u DI v we obtain. Lens manufacturers commonly use the lens maker formula for manufacturing lenses of the desired focal length.
Let us consider the thin lens with 2 refracting surfaces having the radii of curvatures R1 and R2 respectively. Derive the relation between object and image distance in terms of refractive index of the medium and radius of curvature of the surface. Equation vii is known as.
CD 2 R 2. 6 33 Show that can not spontaneously emit a proton. It is the lens makers formula where lens is the convex lens in this case.
It is so called because it is used by lens manufacturers to make lenses of particular power from the glass of given refractive index. Asked Jun 10 in Physics by Maanas 259k points class-12. Basic assumptions in derivtion of Lens - makers formula.
