A parallel beam of light is incident on a prism as shown in figure. Such that the rays get reflected from opposite faces. The angle of deviation `delta` between reflected rays from faces AB and AC is-

The path of a ray of light passing through an equilateral glass prism ABC is shown in figure. The ray of light is incident on face BC at the critical angle for just total internal reflection. The total internal reflection. The total angle of deviation after the refraction at face AC is 108^@ . Calculate the refractive index of the glass.
