Question
A bi-convex lens is formed with two thin plano-convex lenses as shown in the figure. Refractive index n ofthe first lens is 1.5 and that of the second lens is 1.2. Both the curved surface are of the same radius ofcurvature R = 14 cm. For this bi-convex lens, for an object distance of 40 cm, the image distance will be
Options
A.- 280.0 cm
B.40.0 cm
C.21.5 cm
D.13.3 cm
Solution
PT = (1.5 -1) 
f = +20 cm
∴ v = 40 cm
f = +20 cm
∴ v = 40 cm
