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 ? |
| Answer» THICKNESS of GLASS slab = d= 2.1cmμ=1.5shift 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 | |
