A) \[1\,\,cm\]upward
B) \[4.5\,\,cm\]downward
C) \[1\,\,cm\]downward
D) \[2\,\,cm\]upward
Correct Answer: A
Solution :
Apparent depth of mark as seen through a glass slab of thickness \[x\] and refractive index\[\mu \] is Apparent depth\[=\frac{\text{Real}\,\,\text{depth}}{\text{Refractive}\,\,\text{index}}\]or\[x'=\frac{x}{\mu }=\frac{3}{1.5}=2\,\,cm\] As image appears to be raised by\[1\,\,cm,\] therefore, microscope must be moved upwards by\[1\,\,cm.\]You need to login to perform this action.
