Slabs In Parallel Combination

A parallel glass slab of refractive index sqrt3 is placed in contact with an equilateral prism of refractive index sqrt2 . A ray is incident on left surface of slab as shown. The slab and prism combination is surrounded by air. The magnitude of minimum possible deviation of this ray by slab-prism combination is:

Thin lens (Part-3)|Finding the refractive index of a liquid using concave mirror| lens mirror combination

A thin convex lens of focal length 'f' is put on a plane mirror as shown in the figure . When an object is kept at a distance 'a' from the lens - mirror combination , its image is formed at a distance (a)/(3) in front of the combination . The value of 'a' is :-

A 20cm thick glass slab of refractive index 1.5 is kept in front of a plane mirror. Find the position of the image (relative to mirror) as seen by an observer through the glass slab when a point object is kept in air at a distance of 40 cm from the mirror.

In previous illustrations if image formed by the mirror coincides with the source and that produced by the combination is produced at a distance 30 cm from the source away from mirror then find the refractive index of the liquid.
