Question

write The Lens Maker Formula and explain the terms in it​

Answer 1

Answer:

$\frac{1}{v} - \frac{1}{u} = ( \frac{n2}{n1} - 1)( \frac{1}{1} - \frac{r1}{r2} )$

where,

v=distance of image formed

u=distance of object

r1=radius of curvature of the lenssurface closest to the light source

r2=radius of curvature of the lens surface farthest from the light source

n=index of refraction

Answer 2

Answer:

here is ur answer mate

Explanation:

A lens maker formula may be defined as the formula which gives the relationship for calculating focal length(f) in term of Radii of the two curvatures of lens that is R1 and R2 and the refractive index of lens and surrounding
