A drop of liquid is spread over the hypotenuse of a right angled isosceles prism as shown in Fig. and a ray of light is incident normally on face `AB` of the prism. If refractive index of liquid is `sqrt(2)`, then for total internal reflection to occur, refractive index of material prism should be :
