A) 68 cm
B) 75 cm
C) 128 cm
D) 34 cm
Correct Answer: D
Solution :
\[\text{n}\,\text{=}\frac{\text{Real depth}}{\text{Apparent}\,\text{depth}}\] \[n=\frac{6}{4}=\frac{3}{2}\] \[\frac{{{n}_{1}}}{u}=\frac{{{n}_{2}}}{v}=\frac{{{n}_{1}}\tilde{\ }{{n}_{2}}}{R}\] \[\frac{1.5}{6}-\frac{4}{17}=\frac{1.5-1}{R}\] \[R=34cm\]You need to login to perform this action.
