There are three optical media 1,2 and 3 with the refractive indices `mu_(1) gt mu_(2) gt mu_(3)`.
(TIR `rarr` total internal reflection)
A. when a ray of light travels from 3 to 1 no TIR will place
B. critical angle between 1 and 2 is less than the critical angle between 1 and 3
C. critical angle between 1 and 2 is more than the critical angle between 1 and 3
D. chances of TIR are move when ray of light travels from 1 to 3 as compared to the case when it travel from 1 to 2
