The radii of curvature here are measured according to the cartesian sign convention.for a double convex lens the radius r 1 is positive since it is measured from the front surface and extends right to the center of curvature. Lens maker formula is used to construct a lens with the specified focal length. flexiprep.com

Lens maker’s formula is a formula that relates focal length. radii of curvature. and refractive index of the lens. If k = − 1 k = − 1. the surface is a paraboloid.

#### N L E N S Is Refractive Index Of Lens N 0 Is Refractive Index Of Surrounding (For Air. N 0 = 1 ) R 1 And R 2 Are Radius Of Curvature Of Each Surfaces.

Please solve the question in the picture. Lens maker’s formula defines a relation between the lens’s focal length. the refractive index of the material used to make the lens. and the radii of curvature of the two curved surfaces. The lens equation 6 2.

#### The Physics Course Is Delivered In Hinglish.

As different devices need lenses of different focal lengths. this formula helps lens manufacturers in finding the radii of curvature. Homework equations focal length is 7.3 find radius focal length x 2=radius. In case of converging lens :

#### Before Understanding The Formula. Let Us Look At Some Terminology You Need To Know.

Let b and d be the poles. c 1 and c 2 be the centres of curvature and r 1 and r 2 be the radii of curvature of the two lens surfaces abc and adc. respectively. F u f v object image The object lies close to principal axis.;

#### Writing The Lens Equation In Terms Of The Object And Image Distances. 1 O + 1 I = 1 F.

Example 1) write the equation of the lens maker formula. An equiconex lens of power p is cut into two equal halves by a plane perpendicular to its principal axis. The relationship between a lens focal length. the refractive index of its material. and the radii of curvature of its two surfaces is known as the lens makers formula.

#### The Radius R 2 Is Negative Since It Extends Left From The Second.

(a) lens maker’s formula : The radii of curvature here are measured according to the cartesian sign convention.for a double convex lens the radius r 1 is positive since it is measured from the front surface and extends right to the center of curvature. If 0 k − 1 0 k − 1. the surface is an ellipsoid.
