If the power of a lens is - 4.0 d

WebAnswer (1 of 3): u= -40 cm , v= 10 cm By lens formula, we get -1/u + 1/v= 1/f 1/40 + 1/10 =1/f 1/f = (4+1)/40 =5/40 =1/8 f =8 cm So P(power) =100/f(in cm) =100/8 = +12.5 D Ans. P = +12.5 D WebSolution Verified by Toppr Given, power of the lens, P=+4D we know that, focal length (f)= P1=0.25 m Given, size of the object = size of the image For convex lens, this condition is possible only When the object is placed at the centre of curvature. ∴ Object distance = 2f=2×0.25 m=0.5 m or 50 cm Was this answer helpful? 0 0 Similar questions
