There is a mark at the bottom of a beaker. A liquid of refractive index 1.4 is poured into it. If the depth of the liquid is 3.5 cm then determine how much will the mark appear to rise when it is viewed from above?

A metal coin at the bottom of a beaker filled with a liquid of refractive index 4//3 to height of 6 cm . To an observer looking from above the surface of the liquid, coin will appear at a depth of (consider paraxial rays).

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 tank is filled with water to a heigth of 12.5 cm. The apparent depth of a needle lying at the bottom of the tank is measured by a microscope t be 9.4 cm. what is the refractive index of water ? If water is replaced by a liquid of refractive index 1.63 upto the same hight, by distance would the microscope have to be moved to focus on the needle again?
