White light is incident on the interface of glass and air as shown in the figure. If green light is just totally internally reflected then the emerging ray in air contains

yellow, orange, red violet, indigo, blue all colours all colours except green

yellow, orange, red

$C=\sin ^{-1}\left(\frac{1}{\mu}\right)$ and in the sequence VIBGYOR, C increases. In this case the angle of incidence is such that it is equal to critical angle for green colour. ∴  (a)
