A concave mirror of focal length 50 cm is placed at origin as shown in diagram. A point sized object is placed at O (x = 152 cm). A glass slab of thickness 4 cm, μ = 2, is placed symmetrically around C. Light can not reach from object to mirror without passing through slab. Choose the CORRECT option(s) :

Derived solution: Step 1: Use Snell’s law at each plane interface. For paraxial viewing through a plane surface, apparent depth = real depth × n(observer)/n(object medium). Step 2: Test each statement independently using these relations and the data/figure. Step 3: The statements that satisfy the required optical conditions are A: Image made by concave mirror will be at x = 75 cm; B: Final image made by entire optical system will be at x = 77 cm.; D: Final image of the system will be virtual..…
