A monochromatic light ray is incident on the refracting face of a prism of angle\[75{}^\circ \]. It passes through the prism and is incident on the other face at the critical angle. If the refractive index of the prism is \[\sqrt{2}\], then determine the angle of incidence on the first face of the prism.
