Question
A ray of light normally on the first refracting face of the prism of refracting angle A. The ray of light comes out at grazing emergence. If one half of the prism (shaded position) is knocked off, the same ray will :-
Options
A.Emerge at an angle of emergence sin-1
B.Not energy out of the prism
C.Emerge at angle of emergence sin-1
D.None of theseNone of these
Solution
μ sin A = 1 × sin 90o × μ =
& μ sin
= 1 × sine = × = sinesine =
⇒ C = sin-1
