A narrow beam of monochromatic light, PQ, is incident normally on one face of an equiangular glass prism of refractive index `1.45`. When the prism is immersed in a certain liquid, the ray makes a grazing emergence along the other face (figure). Find the refractive index of this liquid .

A narrow beam of monochromatic light, pe, is incident normally on one face of an equiangular glass prism of refractive inder 1-45. When the prism is immersed in a certain liquid, the ray makes a grazing emergence along the other face (See below figure). Find the refractive index of this liquid.
