A) 2 cm upward
B) 1 cm upward
C) 45 cm downward
D) 1 cm downward
Correct Answer: B
Solution :
Apparent depth of mark as seen through a glass stab of thickness \[x\] and refractive index \[\mu \] is Apparent 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 upward by\[1\,\,cm\].
