In the figure, a ray is incident on one face of a triangular prism in air. The angle of incidence \( \theta=37^{\circ} \) is chosen so that the emerging light ray also makes the same angle \( \theta \) with the normal to the other face. If the apex angle \( \phi \) is \( 52^{\circ} \), what is the index of refraction of the prism material? Number Units
