An object P is focussed by a microscope M. A glass slab of thickness 2'1 cm is introduced between P and M. If the refractive index of the slab is P5, by what distance should the microscope be shifted to focus the object again ?

An object P is focussed by a microscope M. A glass slab of thickness 2.1 cm is introduced between P and M. If the refractive index of the slab is 1.5, by what distance should the microscope be shifted to focus the object again ?

A glass is filled with water up to 12.5 cm. The apparent depth of an object lying at the bottom of the glass is measured by a microscope to be 9.4 cm. Calculate the refractive index of water. If water is replaced by a liquid of refractive index 1.63 up to the same height, by what distance would the microscope has to be moved to focus the object again?

A glass slab (mu=1.5) of thickness 6 cm is placed over a paper. What is the shift in the letters?

A microscope is focussed on a mark on a piece of paper and then a slab of glass of thickness 3 cm and refractive index 1.5 is placed over the mark. How should the microscope be moved to get the mark again in focus ?
