A) \[0{}^\circ \]
B) \[60{}^\circ \]
C) \[45{}^\circ \]
D) \[30{}^\circ \]
Correct Answer: C
Solution :
For critical angle \[Sin\,\,C=\frac{1}{\mu }\] \[\sin \,C=\frac{1}{\sqrt{2}}=\sin {{45}^{o}}\] \[C={{45}^{o}}\] it means angle of emergence \[e={{45}^{o}}\] For prism angle of incident I = \[e={{45}^{o}}\]You need to login to perform this action.
