Verified Answer
A beam of light consisting of red, green and blue colours is incident ...
For total internal reflection
i.e. for an angle of incidence of 45°, that colour will suffer total internal reflection for which the refractive index is less than 1.414.
Therefore, red light will be refracted at interface AB whereas blue and green light will suffer total internal reflection.
