A) \[60{}^\circ \]
B) \[30{}^\circ \]
C) \[45{}^\circ \]
D) The ray will not emerge out of his prism
Correct Answer: D
Solution :
We have, \[\delta =(\mu -1)A\] \[=(1.5-1)\times 90\] \[=0.5\times 90\] \[={{45}^{o}}\] Now, \[\delta =({{i}_{1}}+{{i}_{2}})-A\] \[\therefore \] \[{{i}_{2}}=\delta -{{i}_{1}}+A\] \[=45-{{30}^{o}}+{{90}^{o}}\] \[={{105}^{o}}\] Angle of emergence has inclination with second surface \[=90-105\] \[=-15\] This shows that light ray will not emerge out of the prism.You need to login to perform this action.
