Three immiscible liquids of densities `d_1 gt d_2 gt d_3` and refractive indices `mu_1 gt mu_2 gt mu_3` are put in a beaker. The height of each liquid column is `(h)/(3)`. A dot is made at the bottom of the beaker. For near normal vision, find the apparent depth of the dot.

Three immiscible liquids of densities d_1 gt d_2 gt d_3 and refractive indies mu_1 gt mu_2 gt mu_3 are put in a beaker. The light of each liquid column is (h)/(3) . A dot is made at the bottom of the beaker. For near normal vision, find the apparent depth of the dot.

Two immiscible liquids of densities d and 2d are taken in a cylindrical vessel with equal heights each h. The velocity efflux of the liquid coming out of the hole made to the wall of the vessel at its bottom is

There are three optical media 1,2 and 3 with the refractive indices mu_(1) gt mu_(2) gt mu_(3) . (TIR rarr total internal reflection)

Two immiscible liquid of densities rho and 3rho are put in a container. The height of each liquid is h. A solid cylinder of length L and density d is put in this container. The cylinder floats completely inside liquids with its axis vertical and length L/3 in the denser liquid. The density d is equal to

Two non-mixing liquids of densities rho and nrho (n gt1) are put in a container. The height of each liquid is h . A solid cylinder of length L and density d is put in this container. The cylinder floats with its axis vertical and length pL(p lt 1) in the denser liquid. The density d is equal to :
