A) \[0{}^\circ \]
B) \[\frac{\pi }{6}\]
C) \[\frac{\pi }{3}\]
D) \[\frac{\pi }{4}\]
Correct Answer: D
Solution :
[d] Apply snell?s law at AB surface \[{{\mu }_{1}}Sini={{\mu }_{2}}Sinr\] \[1\,\sin i=1.41\,\sin \,30\] \[Sini\,=\sqrt{2}\frac{1}{2}\] \[Sini\,=\frac{1}{\sqrt{2}}\] \[i=45{}^\circ \,or\,\frac{\pi }{4}\] Note: Question asked in prism required basic knowledge of GeometryYou need to login to perform this action.
