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 \[\text{Apparent}\,\text{depth}\,\text{=}\,\frac{\text{Real}\,\text{depth}}{\text{Refractive}\,\text{index}}\] 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.
