begin mathsize 14px style 1 over f equals space left parenthesis space mu minus 1 right parenthesis open parentheses 1 over R subscript 1 plus 1 over R subscript 2 close parentheses end style
 
where μ is refractive index of material of lens , R1 and R2 are radii of curvature of spherical surface .

A tree is 18.0 m away and 2.0 m high from a concave lens. How high is the image formed by the given lens of focal length 6 m ? Ans is Focal length of the lens is f = -6.0 m, u = -18 m and h = 2 m ?1v=1f+1u=1(?6.0)?118.0?v=?4.5m ? The image size, h'= h [?vu]=2×[??4.518.0]=0.50m My doubt is the magnification is v/u for lens right?
