Question

о
a point object is placed in air at a distance
of 40 cm from a concave refracting surface of material of refractive
index 15. Find the position of the image of the radius of curvature
is 10cm.​

Answer 1

Answer:

Refractive index n of the first lens is 1.5 and that of the second lens is 1.2. Both the curved surfaces are of the same radius of curvature R = 14 cm. For this bi-convex lens, for an object distance of 40 cm, the image distance will be.
