A) \[2C\]
B) \[\frac{\pi }{2}-C\]
C) \[\pi -C\]
D) \[\pi -2C\]
Correct Answer: B
Solution :
\[OA\text{ }=\]incident ray \[\Delta S=\]interface which separates the two medium. \[OB=\]actual path of the incident ray. \[\angle C=\]critical angle. \[\angle QOB\]is also \[=\angle C\] After incidence ray refract towards OS. \[\therefore \]Deviation \[(\delta )=\angle BOS\] \[=\frac{\pi }{2}-C\]You need to login to perform this action.
