A) \[0.06\,\,m\]
B) \[0.17\,\,m\]
C) \[0.05\,\,m\]
D) \[0.04\,\,m\]
Correct Answer: A
Solution :
Refractive index\[=\frac{real\,\,depth}{apparent\,\,depth}\] \[\therefore \] \[\frac{x}{0.04}=\frac{0.21-x}{0.10}\] \[\Rightarrow \] \[0.12\times 0.04-x\times 0.04=0.10x\] \[\Rightarrow \] \[x=\frac{0.21\times 0.04}{0.14}=0.06\,\,m\]You need to login to perform this action.
