A point object is placed at a distance of 25cm from a convex lens. Its focal length is 22cm. A glass slab of refractive index 1.5 is inserted between the lens and the object, then the image is formed at infinity. Find the thickness of the glass slab (in cm).

A point object O is placed at a distance of 41 cm from a convex lens of focal length f = 20 cm on its principal axis. A glass slab of thickness 3 cm and refractive index mu = 1.5 is placed between the lens and the object with its faces perpendicular to the principal axis of the lens. Image of the object is formed at point I_(1) . Now the glass slab is tilted by an angle of theta = 1° (as shown in the Figure) and the final image is formed at I_(2) . Calculate the distance between points I_(1) and I_(2) . Consider only paraxial rays for the lens and near normal incidence for the glass slab.
