The refractig angle of a prism is A and the refractive index of its material is mu .When a ray of light is incident on the face AB of the prism,after refraction through the prism,the ray of light just grazes along the face AC as shown in Fig.3.21. Determine the value of the angle of incidence in terms of A and mu .

The refrating angle of a prism is 40^@ and the refractive index of its material is given by mu=1.25 + b/(delta^2) When a ray of light is incident normally on the face AB of the prism,after refraction through the prism,the ray of light just grazes along the face AC as shown in Fig.3.20. . Find the critical angle for the material of the prism.
