Question
A ray of light travels from an optically denser to rarer medium. The critical angle for the two media is C. The maximum possible deviation of the ray will be :-
Options
A.
B.2C
C.π - 2C
D.π - C
Solution
When the ray passes into the rarer medium, the deviation is δ = φ - 0. .This can have a maximum value of
for θ = C and f = 
When total internal reflection occurs, the deviation is δ = π - 2, the minimum value of θ being C. The maximum value of δ = π - 2C.
