A point object O is placed at a distance of 62 cm in front of a concave mirror of focal length f = 20 cm . A glass slab of refractive index mu = (3)/(2) and thickness 6 cm is inserted between the object and the mirror. Let’s define final image as image formed after the light ray originating from O passes through the slab, gets reflected from the mirror and then again passes through the slab. At what distance d from the mirror, the face AB of the slab can be placed so that the final image is formed inside the slab itself?
