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