A convexo-convexhas a focal length of f_1=10 cm. One of the lens surfaces having a radius of curvature of R=10 cm is coated with silver. Construct the image of the object produced by the given optical system and determine the position of the image if the object is at a distance of a=15 cm from the lens. Refractive index of lens =1.5. |

Answer» `1/10=(1.5-1)(1/(R_1)-1/(-10))` `:. R_1=+10 cm` Now, using, `1/v+1/u=(2(n_2//n_1))/(R_2)-(2(n_2//n_1))/(R_1)` SUBSTITUTING the VALUES, `1/v-1/(-15)=(2(1.5))/(-10)-(2(1.5-1))/(+10)` `:. v=-2.14 cm`
