Unique Derivation For Lens Maker Formula
In this video learn how to derive lens maker formula for thin lens.
Derivation for lens maker formula. 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. The Lens Makers Formula Lens manufacturers use the lens makers formula to manufacture lenses of the desired focal length. Hence obtain the expression for lens-makers formula in the case of thin convex lens.
It is where the lens formula comes into the action. The derivation of lens maker formula is provided here so that aspirants can understand the concept more effectively. Asked Oct 18 2019 in Physics by KumarManish 577k points cbse.
Lens makers formula. Amansinha1253 amansinha1253 25092020 Physics Secondary School 5 pts. So to derive the lens makers formula you first need to derive the relation between object and image distance in terms of refractive index of the medium and the radius of curvature of the curved spherical.
A concave lens diverges the parallel beam of light at the focal point and bends the light rays outward. The lens maker formula is commonly used by lens manufacturers for manufacturing lenses of desired focal length. Derivation of Lensmakers formula.
We will discuss the form of the equation that is applicable only to thin lenses. Answered Derive lens maker formula 2. Derivation of Lens Formula The lens formula establishes the relation between the object and image distances from the optical center and the focal length of a lens.
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. As per optical physics lens formula relates the distance of an object u the distance of an image v and the focal length f of the lens. Derive the relation between object and image distance in terms of refractive index of the medium and radius of curvature of the surface.
