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 = \[\frac{\text{Real}\,\text{depth}}{\text{Refractive}\,\text{index}}\] \[\text{or}\text{x }\!\!'\!\!\text{ =}\frac{\text{x}}{\mu }=\frac{3}{1.5}=2\,cm\] As image appears to be raised by 1 cm, therefore, microscope must be moved upward by 1 cm.You need to login to perform this action.
