A) Less than 1.41
B) Equal to 1.41
C) Greater than 1.41
D) None of the above
Correct Answer: C
Solution :
For total internal reflection \[\theta >C\] \[\Rightarrow \] \[\sin \theta >\sin C\Rightarrow \sin \theta >\frac{1}{\mu }\] or \[\mu >\frac{1}{\sin \theta }\Rightarrow \mu >\frac{1}{\sin {{45}^{o}}}\Rightarrow \mu >\sqrt{2}\]\[\Rightarrow \]\[\mu >1.41\]You need to login to perform this action.
