A) \[\frac{\sqrt{2}+1}{2}\]
B) \[\sqrt{\frac{3}{2}}\]
C) \[\sqrt{\frac{1}{2}}\]
D) \[\sqrt{2}+1\]
Correct Answer: B
Solution :
At point A, by Snell?s law \[\mu =\frac{\sin 45}{\sin r}\]\[\Rightarrow \sin r=\frac{1}{\mu \sqrt{2}}\] .....(i) At point B, for total internal reflection \[\sin {{i}_{1}}=\frac{1}{\mu }\]You need to login to perform this action.
