364915 A glass slab of thickness \(3\;cm\) and refractive index \(3{\rm{/}}2{\rm{ }}\) is placed on ink mark on a piece of paper. For a person looking at the mark at a distance \(5.0\;cm\) above it, the distance of the mark will appear to be

364916 The image of point \(P\) when viewed from top of two identical slabs having thickness \(2\;cm\) will be :

364917 In a vessel two immiscible liquids are filled as shown in the figure. The effective refractive index of the combination for normal view is

364918 A rod of height \(h\) is placed in a beaker of same radius. The height of the beaker is thrice its radius. An observer sees the top end of the rod through a pin-hole (see figure). When the beaker is filled with a liquid \(\left( {R.I. = \sqrt \mu } \right)\) upto a height 2h, he can see the lower end of the rod. Find the value of \(\mu \).
