The power of a convex lens of focal length 5 cm is?
It is given that,Focal length of the convex lens, f = 5 cmTo find,The magnifying power of the lens.Solution,The formula of the magnifying power of a lens is given by :D is the least distance of distinct vision, D = 25 cmm = 1 + 25/5 = 1 + 5m = 6The magnifying power of the convex lens is 6. Hence, this is the required solution.
Dear student Here, f=5cm,d=25cm,m=?m=(1+d/f)=(1+25/5)=6.///////////////////////////////////////////////
