An object P is focused 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 ?

Given :
Thickness of glass slab = d= 2.1cm
μ=1.5
shift due to glass glass slab:
dt=[1-(1/μ)]d
=[1-(1/1.5)x 2.1
=1/3(2.1)
=0.7cm
∴The microscope would be shifted to 0.7cm to focus the object

Answer is explained below:-
Thickness of glass slab = d= 2.1cm
μ=1.5
shift due to glass glass slab:
dt=[1-(1/μ)]d
=[1-(1/1.5)x 2.1
=1/3(2.1)
=0.7cm
∴The microscope would be shifted to 0.7cm to focus the object
