Find the apparent depth of an object O placed at the bottom of a beaker as shown in which two layers of transparent liquids are filled

[22.67 cm]

Find the apparent depth and apparent shift of an object placed at the bottom of the vessel containing a glass slap of thickness 10 cm and water of height 50 cm. as shown in the figure.

Find the apparent depth of object O below surface AB , seen by an observer in mediumn of refractive index mu_(2)

Water is filled up to a height of 13 cm in a jar. Apparent depth of a point placed at the bottom is measured by a microscope and it found to be 10 cm. What is refractive index of water? Now water is replaced by another liquid of refractive index 1.6 up to the same height. By what distance must the microscope be moved in order to focus at the point on the bottom of jar?

The apparent depth of an object at the bottom of tank filled with a liquid of refractive index 1.3 is 7.7 cm. what is the actual depth of the liquid in the tank ?

A tank of height 33.25 cm is completely filled with liquid ( mu = 1.33). An object is placed at the bottom of tank on the axis of concave mirror as shown in the figure. Image of the object is formed 25 cm below the surface of the liquid, then focal length of the mirror is

While determining the refractive index of a liquid experimentally, the microscope was focussed at the bottom of a beaker, when its reading was 3.965 cm. on pouring liquid upto a height 2.537 cm inside the beaker, the reading of the refocussed microscope was 3.348 cm. Find the refractive index of the liquid.

A real image of an object is formed by a conex lens at the bottom of an empty beaker. The beaker is now filled with a liquid of refractive index 1.4 to a depth of 7 cm. In order to get the image again at the bottom the beaker shoud be moved

A transparent solid sphere of radius 2 cm and density rho floats in a transparent liquid of density 2rho kept in a beaker. The bottom of the beaker is spherical in shape with radius of curvature 8 cm and is silvered to make it concave mirror as shown in the figure. When an object is placed at a distance of 10 cm directly above the centre of the sphere C, its final image coincides with it. Find h (as shown in the figure ), the height of the liquid surface in the beaker from the apex of the bottom. Consider the paraxial rays only. The refractive index of the sphere is 3//2 and that of the liquid is 4//3.

A tank filled with a liquid to a height of 12.5 cm. The apparent depth of a needle lying at the bottom of the tank is measured by a microscope to be 10 cm. If water is replaced by water of refractive index 1.66 up to the same height, by what distance (in mm) would the microscope have to be moved to focus on the needle again?
