In a vessel, as shown in Figure., point P is just visible when no liquid is filled in vessel through a telescope in the air. When liquid is filled in the vessel completely, point Q is visible without movint the vessel or telescope. Find the refractive index of the liquid.

A person looking through a telescope T just sees the points on the rim at the bottom of a cylindrical vessel when the vessel is empty. When the vessel is completely filled with a liquid (mu, = 1.5) , he observes a mark at the centre B,of the bottom without moving the telescope or the vessel. What is the height of the vessel if the diameter of it scross section is 10cm.

A person looking through a telescope focuses the lens at a point on the edge of the bottom of an empty cylindrical vessel Next he fills the entire vessel with a liquid of refractive index mu , without disturbing the telescope.

A vessel of height 2d is half-filled with a liquid of refractive index sqrt(2) and the other half with a liquid of refractive index n. (The given liquids are immiscible). Then the apparent depth of the inner surface of the bottom of the vessel (neglecting the thickness of the bottom of the vessel) will be

A cylindrical vessel of radius r containing a liqiud is rotating about a vertical axis through the centre of circular base, If the vessel is rotating with angular velocity omega then what is the difference of the heights of liquid at centre of vessel and edge?

A thin equiconvex lens of refractive index 3//2 is placed on a horizontal plane mirror as shown in figure. The space between the lens and the mirror is filled with a liquid of refractive index 4//3 . It is found that when a point object is placed 15 cm above the lens on its priincipal axis, the object coincides with its own image. Q. If another liquid is filled instead of water, the object and the image coincide at a distance 25 cm from the lens. Calculate the refractive index of the liquid.

An observer can see through a pin-hole the top end of a thin rod of height h, placed as shown in the figure. The height of beaker is 3h and its radius is h. When the beaker is filled with a liquid up to a height 2h , he can see the lower end of the rod. Then the refractive index of the liquid is
