A) 0.06 m
B) 0.17 m
C) 0.05 m
D) 0.04 m
Correct Answer: A
Solution :
\[\text{Refractive}\,\text{index}\,\text{=}\,\frac{\text{real}\,\text{depth}}{\text{apparent}\,\text{depth}}\] \[\therefore \] \[\frac{x}{0.04}=\frac{0.21-x}{0.10}\] \[\Rightarrow \] \[0.21\times 0.04-x\times 0.04=0.10x\] \[\Rightarrow \] \[x=\frac{0.21\times 0.04}{0.14}=0.06\,m\]You need to login to perform this action.
