Q.
If a white light incident on the interface of glass and air as shown in figure and green light is just totally internally reflected, then the emerging ray in air contains
Since the green light is totally internally reflected hence for green ray the given angle of incidence is just equal to critical angle ie,
$sin\, i = \frac{1}{n_g}$
For yellow, orange and red rays refractive indices will be less than $n_g$ and hence these rays may emerge in air.
