Pls solve e pls .....
Dear Student
I. 90o
II. The angle through which the incident ray deviates and emerges out of the prism is 90°.
III.
The surface AB of the prism behaves as a mirror as for it light is totally reflected not refracted.
IV. Critical angle is equal to 45 degree.
As here at incidence angle 45 degree light is going through internal reflection.
Regards
