Matchless Lens Maker Formula Wikipedia
N is the refractive index of the material used.
Lens maker formula wikipedia. LENS MAKERS FORMULA Video Lecture of Physics for IIT-JEENEETBOARDS Class XI- XII by SHAILENDRA Sir. The Lens Makers formula for a thin lens is as follows. Short derivation of the lens maker formula using curved surface refraction formula.
A lens having at least one convex surface such that light passing through it may be brought to a focus. Simple thin lenses are designed by using the so-called lens-makers formula. It may be written as.
1Let R 1 and R 2 be the radii of curvature of two spherical surfaces ACB and ADB respectively and P be the optic centre. The Lens Makers Formula. Learn lens makers formula.
A lens will be converging with positive focal length and diverging if the focal length is negative. R1 is positive R2 is negative and f. The lens makers equation is another.
Using the formula for refraction at a single spherical surface we can say that For the first surface Therefore we can say that Where μ is the refractive index of the material. The power of a lens is given by the equation latextextPfrac1textflatex. The following assumptions are taken for the derivation of lens maker formula.
Let us consider a thin lens made up of a medium of refractive index. The derivation of lens maker formula is provided here so that aspirants can understand the concept more effectively. Lens Maker Formula Derivation.
