A) \[\mu =1.33\]
B) \[\mu =1.40\]
C) \[\mu =1.50\]
D) \[\mu =1.25\]
Correct Answer: C
Solution :
For total internal reflection \[i>c\] \[\Rightarrow \] \[\sin i>\sin c\] \[\Rightarrow \] \[\sin {{45}^{o}}>\frac{1}{\mu }\] \[\Rightarrow \] \[\mu >\sqrt{2}\] \[\Rightarrow \] \[\mu >1.4\]You need to login to perform this action.
