A ray of white light is incident on the interface of glass and air as shown in the figure. At the given angle of incidence, green light suffers total internal reflection. The rays emerging out from glass to air contain :
- yellow, orange and red colours
- violet, indigo and blue colours
- all colours
- all colours except green
How is the critical angle related to the refractive index of a medium?
