On a right angled transparent triangular prism ABC , when a ray of light is incident on face AB , parallel to the hypotenuse BC , it emerges out of the prism grazing along the surface AC . If instead the ray is made incident on face AC , parallel to the hypotenuse CB it gets totally reflected on face A B . The refractive index of the material of the prism is
